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!

Review highlights

Reviews

Great customer service

"First, my Monster Mashup case is so cute! Fits well, protects the screen on the corners and the side buttons are easy to push. Unfortunately, my original delivery never made it to me. The Casely team immediately fixed it and sent me a replacement. Because of this, I will only buy cases from here going forward."

— Joselle P. (5/5)

Great cases. Rewards are a little confusing

"Love my cases. Only problem is I don't know how to use my rewards and I have over 2,000 of them and when I try to put them in when I place an order over $100 they don't show up so I'm going to lose them. I was just hoping I could get a couple of cases and call it a day but I guess I have to buy more in order to get the rewards"

It’s perfect!

"I’m overly obsessed. It fits so perfectly on my phone. It’s not bulky and the design is amazing. The MagSafe works and the general of the case is what I was hoping for."

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.
