What's the difference between the Bold & the Bold Flex? The Bold Flex is a slightly more flexible version of our ultra-protective Bold case, featuring two detachable layers of protection.

Plus, we’ve added small slits to the Bold Flex case buttons, making them softer and more responsive to touch. It’s an upgrade you’ll appreciate with every press!

Nice cover

"I purchased this for my husband’s new phone and he seems very happy with it. The case is protective but not overly bulky."

Courtney P. (5/5)

Yessss

"It’s cute black case. I love how sleek black on black looks. It looks adorable on my black iPhone!"

J (5/5)

The structure feels great and

"The structure feels great and I like the texture. Buttons easily allow me to access the necessary elements. On one side of the case, it does not hug the phone in fullness the way I want it to, and this leaves slight room for dust etc to get in. Other than that, MagSafe element is strong and durable which I appreciate. Would maybe buy again to see if gap issue is one time or all the time"

About the Black Onyx | The Boyfriend Collection

Go back to the basics with Casely's Black on Black case from The Bold Collection. The simple, sleek look goes great with any outfit and lets people know you mean business. As minimalistic as this case appears, it is designed to protect your phone from drops and falls. The Bold Collection's Black on Black case is engineered with four inside air pockets that absorb impact in the event your phone slips out of your hand. This is unlikely, however, considering the case has a soft side grip. Additionally, the front lip is raised by 3mm to further protect your screen from unwanted cracks and scratches when you set it face down. Casely's Black on Black case from The Bold Collection protects your phone while retaining its usability. The embossed buttons make it easy to use your phone as you normally would. So, turn up the volume and let everyone know how awesome your new phone case is!

Please note: Our Bold Flex (+ MagSafe®) and Essential (+ MagSafe®) cases are made to order. Due to the unique printing process and materials, there may be a slight variation in how the colors appear compared to the digital product photos. 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.
