STRONGEST HOME brand door handle stopper set is just what we needed~ Our doors kept on banging onto the wall and causing scuff marks and dents and we aren't too thrilled about that. With the help of the white silicone door knob stopper set we are relieved~ This set has 7 pieces of the silicone door knob stoppers and each is about 1.6 inches in diameter. They are easy to apply. Just peel off the double sided tape on the back of the stopper and stick it onto the wall where the door knob will hit against. It's that simple and efficient. No more worrying the wall will be damaged. Good value~
