Pads have a self-stick adhesive backing with release paper. Protect furniture and floors from damage! These felt protectors attach to the bottom of almost any surface to protect desktops, tables, counters, hardwood floors, and more from scratches and dings. Packs come assorted in 27-pieces in various sizes and shapes. On wood furniture, prepare surface for installation by cleaning and lightly sanding to ensure better adhesion of the pads. Remember to check periodically for wear and replace pads when appropriate. Instructions for use graphics on package back
