With the OXO StrongHold Suction Corner Basket, you can keep your bath and shower basics organized and at hand. No tools are needed to install, since the Stores lever-activated, phthalate-free StrongHold suction cups adhere the basket securely to tile, glass and other smooth, non-porous surfaces. To adjust or remove, simply flip the lever to deactivate the suction. The suction cups slide to avoid grout lines for installation. Bottle holes store shampoo, conditioner, and body wash upside down, so you don’t waste a drop. For best results, use on smooth glazed surfaces, mirrors or glass. Not recommended for use with textured or porous surfaces including some stone, acrylic or metal.
