Review on 📱 Black Hexagon Cell Phone Grip Decal Stickers - Anti-Slip Tape for Phone, Mouse, Laptop, Tablet, Gaming Case Crafting by Jeff Callier

These stickers should be made of softer rubber. It actually looks like hard plastic if there were big sheets to glue onto the steps that would hold your boots but it's not at all what helps you hold a cell phone it's a rough material but Your fingers slide right over it. . You don't want to hit it with your knuckles as it can be very rough on your joints, but it's not grippy. Too bad.
