These are pure silicone bumper pads with 3M professional adhesive backing. They are great for protecting and preventing scratches on cabinets, drawers, doors, countertops and desks, appliances, glass and stone surfaces, and electronics. The solid silicone is also excellent at reducing noise from shutting doors and drawers. Bumpers are 3mm thick and 10mm in diameter (almost exactly 1/8" by 3/8"). Manufactured in 5x10 sheets. 3M adhesive is applied to the bottom of each pad, which can be easily removed from the sheet and applied where needed.
