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!
