A PopSocket is a plastic circle that is sticky-adhered to the back of a flat phone (or case). The PopSocket expands like a small accordion when you pull or "pop" it out two times. This enables you to place your fingers between your phone and completion of the PopSocket for a more comfy and safe and secure hold.PopSockets are divided into two parts: the base (the sticky disc) and the PopTop (the design portion). While the PopTop section is simple to remove after you have actually had enough of it, getting rid of the structure is a little harder.
