This is the best case!

"This is the best case! I love how it’s super supportive, but is not too bulky/thick. I was worried about how the color might come out, buts it’s absolutely perfect!"

"I love my case. It feels durable but still stylish. Shipping was very fast. This is my third case from Casely and I have not been disappointed yet."

Great Case!

"This is my first case from Casely and so far it’s working really well! It seems to be very good quality and sits well on my phone. Interestingly, my case came in a slightly different color than is pictured here, it’s more of a turquoise than the darker ocean blue shown in the photos online. As a fan of the color turquoise I’m completely fine with this and will still be keeping the case as is, but if you’re particularly attached to the darker color palate the potential for the brighter color might present an issue."

Casely quality case

"This was my first purchase of Casey products and I am delighted with this product. It is a great quality case with features sometimes difficult to find. It has an edge on the sides that sit higher than the phone thus giving your phone extra protection. I will definitely look for more products through Casey!"

Are the power cases compatible with my corded headphones?
Yes!
Hello, third time I am asking, trying to figure out what color the grip/lip color is on this for galaxy s10. Is it clear or white? Thank you.
Hey! The grip/lip color for that case will be clear!

Will Casely be making Bold and Power cases for the iPhone 11 Pro Max?

About the Deep Sea | Blue Marble Case

This eye-catching cute blue marble phone case features a range of beautiful blue colors that will make your phone stand in a crowd! Interested in black marble as well? Click to see! This elegant blue marble phone case is a unique and beautiful piece to add to any phone. The coloration of the case has a blueish gray base with accents of light pink. The marbled texture exudes a luxurious style that matches well with gold and blue. The case can be purchased for seven generations of iPhones, and its style and look does not detract from its ability to keep your iPhone safe! The edges are specifically designed to prevent screen cracking and button breaking if the phone were to be dropped. This phone really has an extravagant pattern, and a color scheme that draws the eye. Its powerful shock absorption combined with its absurdly cute color scheme makes this the perfect phone case for chill night on the town, or a rager with the friends! The eye-catching pattern seems almost ethereal and can complement both simple and more elegant outfits.

In addition, differences in screen resolution, brightness, and other settings may cause colors to look a little different in person. These small variations are completely normal and are part of what makes your case one of a kind.
