Made from silicon these round pads are attached to the rear bottom of picture frames, where the frame touches the wall.
Your picture is secure and the pad provides the wall surface with a soft cushion affect. Walls are not marked and as an added benefit adjustments to viewing angles of your frames are not required as often. No need to use commercial type putties like plasticine and other similar products which leave marks and a mess. 

Sold in sheets with 56 individual bumpstop pads
