Keep your bath accessories in reach with The Kenney® suction cup hook set. this set includes three 2.125" diameter suction cup hooks to hold loofahs, sponges, clothes, and more. they can be used on any flat, non-porous surface such as glass, mirrors, or tile. Hanging your items after use lets them dry out between use, making them last longer and helping prevent the buildup of mold and mildew. made of durable and clear plastic, you'll never worry about rust—no matter how long or often you use these hooks. Suction hooks are easy to install, simply apply pressure to the center of the cup and then pull down hook to lock into place. and it's just as easy to reposition or take them on the go; just pull the hook back up and remove from the wall.
