Can be re-positioned many times and removed without leaving residues. Make your home look clean and neat. High Quality Material Soap case are made of pollution-free ABS material, tasteless and durable enough for long-term use. How to Use: Clean the wall and keep it dry. Buckle up the soap dishes. Take off the protective cover on the suction cup. Push the suction cup to the wall with your PALM(not fingers), until you hear a sound "puff". Suitable Surface Suction works best on ceramic tile, glass, mirror, stainless steel, acrylic, plastic, laminate and any non-porous smooth surfaces.
