This suction cup soap holder provides a simple, tool-free option for keeping bar soap accessible in the shower or on smooth interior walls. It works best on non-porous surfaces such as glass, mirrors, polished metal, stainless steel, plastic boards, and wall tiles. Avoid mounting on grout lines or porous surfaces like wallpaper, painted walls, wood, unfinished stone, or natural stones. To install, choose a clean, dry surface, remove the protective cover, press the suction cup firmly until you hear a puff, and the unit is set. If you encounter initial suction issues, wash the cup, dry it, and test on a smooth surface before final placement. A patented bionic design inspired by octopus tentacles enhances suction and durability, and the part is built to withstand wet and oily conditions. The holder supports up to about 11 lbs., providing stable placement for a range of soap sizes. It is made from rust-resistant stainless steel, with a hollow drainage channel to help soap dry between uses. When relocation is needed, detach the suction cup with a card, rinse with warm water, and re-seat on a new smooth surface. This setup works well in apartments, condominiums, and rental properties where permanent fixtures are not desired, and it accommodates different soap sizes as needed. Color: Black.
