Its silicone construction makes it flexible, allowing for frequent placement and removal, unlike a plastic one that may wear out. The downside of silicone compared to plastic is that it does not clean easily if it gets dirty, as it absorbs dirt. It has an integrated strap so you can hang the phone around your neck or wear it crossbody, which helps you not to have it in your hands all the time, but always available when you want to use it. Also useful when the device is too large for your pockets and you don't have a bag to store it in.
