Bought this for my girl friend and her friends as I was hosting a birthday party at a bowling alleyThis just wraps around your finger and nails to make them not catch on the ball as easyNOT ONE SINGLE BROKEN NAILI will mention 2 of them complained ONCE their nail bent a bit and it hurt for a second BUT once the tape was removed the nails for the whole group were still in-tact, no breaks, cracks, polish removal etcworked fantastic
