Customers often say the pearlescent abalone colors look even better in person than in photos. Many like the rectangle shape, which feels different from typical cases, and report the case holding up well through repeated drops. Reviewers say MagSafe works reliably with chargers and stands, describe a snug fit on their iPhone, and mention getting compliments regularly. Several also call it good value next to pricier alternatives.

“Beautiful! Feels very sturdy and rugged. Fits nicely perfect with a full camera protector. Buy it!”

“Beautiful phone case, I’ve had it for about 5 months now. Very sturdy and striking.”

— Skylar

“Absolutely beautiful and great quality. Had to return cuz I bought the wrong size for my mom. But totally worth the money- I can tell.”

— Lily

Is the Abalone Shell case matte or gloss?

Gloss. The Abalone Shell case has a smooth, reflective surface that shows its iridescent shimmer with depth and wipes clean easily. Underneath, it has the same reinforced rectangle corners, raised screen and camera edges and MagSafe magnet ring as every other COCOMII case.

How protective is the Abalone Shell case?

The Abalone Shell case is drop-tested to 10 feet. Its rectangle corners are reinforced, because corners take most of the impact when a phone lands, and the edges are raised above both the screen and the camera lenses, so neither touches the surface when the phone is lying face down or face up on a table.

Is the Abalone Shell case MagSafe compatible?

Yes. The Abalone Shell case has a MagSafe magnet ring built into the back, so MagSafe chargers, wallets and the COCOMII ring holder snap on and hold. Wireless charging works with the case on, so there is no need to take it off to charge overnight. The ring also keeps the phone centred on a MagSafe charger.

Will the Abalone Shell case fit my iPhone?

Choose your iPhone model in the selector before adding the case to your cart. Shared-fit options include iPhone 18 Pro Max / 17 Pro Max, iPhone 18 Pro / 17 Pro, iPhone 14 / 13, and iPhone 12 / 12 Pro. All other listed options are designed for the model shown. If you're unsure which iPhone you have, check Settings → General → About.

What is a rectangle iPhone case?

A rectangle case has flat sides and right-angle corners instead of the rounded profile of most iPhone cases. The Abalone Shell case is one: the flat edges give your fingers a defined edge to grip, and the reinforced corners are part of how it passes a 10-foot drop test. Edges sit above the screen and camera, and MagSafe works through the back.

Stylish, Unique & Secure Phone Case!

I absolutely love this phone case! The holographic shine is gorgeous—it catches the light beautifully and makes it stand out from every other case I’ve owned. I also love the rectangular shape, which feels so modern and unique. I’ve already gotten several compliments on it! The flexible plastic makes it easy to put on and take off, but it still feels very sturdy and protective. My phone feels completely secure inside the case. The MagSafe magnet could be just a little stronger for holding my pop socket accessory, but honestly, that’s a small detail compared to how fabulous this case is overall. If you want something that’s stylish, functional, and a bit different from the average phone case, this one is a winner. Highly recommend!

Better alternative to another brand cases

The “another brand” case company has a case just like this and it’s why I bought this cheaper version. It arrived with one day shipping - already beating another brand who claims their cases are made in NYC but it’s shipping from UTAH LOL. I got this case a few days ago and I’ve been in love with it because I couldn’t stand the otterbox case I had bought at T-Mobile to hold me over. I’ll admit I had ordered a another brand case that looks different to this one - I may keep this case on though until it doesn’t look cute anymore because it’s that good though. Either way 10/10 on this case!!! Edit: I received my another brand case. I am DISAPPOINTED AND SWEAR BY THIS CASE BRAND EVEN MORE. I paid 40 bucks for another brand to feel Less protective than this brand!! Sadly I did give this case to my clients mother but it’s okay - she was so happy it was worth it! I bought another one in black though so I’m excited to receive it and give my another brand case to a friend who will appreciate it more than me 🤣😅

Pretty case!

I love the look of this phone case! It fits my iPhone 16 Pro Max perfectly and looks super sleek. I really like the Rectangled edges. My husband actually makes fun of me and says my iPhone now looks like an Android. He's not exactly wrong, but I like the way it looks!The MagSafe works perfectly on my regular charger. I've dropped my phone a few times since putting this case on and haven't had any damage.Overall, this is a fun case and a great value!

LOVE this case!

I ordered another case from this brand in white and loved it so much that I wanted the darker one as well. The quality is on par with much more expensive cases that look exactly the same. The case allows for easy and unobstructed access to all buttons on my iPhone 16 Pro with no issues whatsoever. Overall, this is a beautiful - high-quality case for a low price. I love it!!! *Highly* recommend!!

Gorgeous

I’ve never had a Rectangle case before and I liked the design of this one so figured I’d give it a shot.I’m IMPRESSED. The case feels incredibly durable, the back is *beautiful* (really looks like a composite of abalone pieces) and is just all around polished and classy looking. It does add some weight to the phone, but so far so in an unpleasant way.I’m super clumsy so we’ll see how it holds up to drops over time, but I think I might look for some more cases!I love this and definitely recommend!!

One of the coolest cases I’ve seen!

This case is perfect for me because one, I love all things beachy and this is pearly shell. So BEAUTIFUL. I’m super clumsy and always dropping my phone. I damage every single phone I get with every yearly upgrade. I am hoping that the reinforced corners will be a good solution for me. I’ve never seen this pretty and I just ordered the matching camera lens protector because I found it by pure luck. It is called Carveit camera cover case colorful shell design, pearl abalone natural white. I also have a screen protector in place, so my phone will be completely armored now 🤣This case is kinda flexible but also seems very strong. It is also magnetic charging base compatible!

Beautiful & Functional

This case fits the iPhone 16 Pro perfectly - cutouts, buttons and all! The back of the case is a hard sturdy plastic, which provides rigidity and protection. The sides are a high quality tpu/silicone type material that flexes and makes it easy to install and remove the case from your phone. On top of that, the opalescent back is gorgeous in or out of the light! No issues with magsafe charging or with magnetic accessories either. This case is excellent for this price point - just get it!!

Phone case

This Rectangle phone case is both a functional and cute way to protect my iPhone 16 ProMax. The Rectangles look is unique and I’ve gotten multiple compliments on it. I love the colors included in the case as well. I would definitely recommend this case and others by Cocomii as a nice way to “dress up” your phone without breaking the bank.

Better in person.

It looks very nice in person. Very shiny, it some what looks like a design that is under a clear resin top coat (even though that’s not what it actually is). I Will order more from this company. Also, the packaging was great, very sturdy box.

Stunning!

I NEVER spend this much on a phone case but it’s totally worth every penny!It’s beautiful and the colors are gorgeous.It’s super shiny and I love that it’s Rectangle.The only thing I don’t like is the name brand at the bottom but it is in gold lettering so it blends in nicely with the colors of the case so that definitely is not a deal breaker.Super easy to put on and all the buttons & openings line up perfectly.

Dupe

This is a really good dupe for another popular brand that makes the Rectangled off phone cases. I think this would make a good gift because it comes so nicely packaged. My only complaint is the logo on the case is much bigger and obvious than in the stock photo.

Didn’t last 3 months

Update: the case didn’t last 3 months. Started to peel and break. :( Initial review: I’m so surprised by this iPhone 15 pro case. Great quality. I thought it was going to be cheapy and plastic, it’s definitely much better than expected. Feels nice, looks nice, durable and the magnet is strong enough in my jeep and doesn’t fall off the dash holder! Highly recommend if you’re going for a chic modern look. So fun

Great looking case

I love this phone case. It’s light and flexible but still very sturdy. It doesn’t feel or look cheap at all. It’s a little translucent. I think it ads to the beauty of the case. My toddler has thrown myPhone a few times and it held up nicely. I will be purchasing from this buyer in the future

Very pretty case

This is a very pretty phone case in person.I ordered the light pink color and it is very, very light pink. In certain lights it almost looks white or translucent, but it is indeed a very soft pink.I really like the Rectangle case. I think that the shape is classy and a little different. Also, it has some extra cushion on the corners in case I drop it.This case works great with my MagSafe chargers in my car and at home. The only thing I may consider is getting another protector for my camera lenses since they’re not as protected with the Rectangle cut-out. But overall, I really like this case. I think it protects my phone well and it looks really nice in person.

Fits great!

I needed a new mag safe friendly case and was excited when I saw this pretty case! It had easy installation and it isn’t terribly hard to remove your phone from either. I like the Rectangle look and it is very pretty. It’s shiny and is easy to find in my purse. It works well with my MagSafe charger in my car and it fits perfectly. Overall very happy with this case!
