Easy to install and reusable suction cup hooks. Simply tear off the film and twist the knob cap counter-clockwise to remove air, then press firmly to the wall and twist clockwise to secure. No drilling, screws, or tools required. These hooks can be used repeatedly after cleaning and drying, leaving no residue or stains. Made with a PVC suction cup base and sticky silicone material for strong adsorption and waterproof capabilities, they are perfect for humid environments. These hooks work best on smooth, clean, flat, and non-porous surfaces like ceramic tile, mirror, glass, and marble. They are not suitable for porous, breakable, uneven, or rough surfaces such as wallpaper, painted walls, or concrete. Made from high-quality stainless steel with a sticky PVC base, each hook can hold up to 9 lbs without losing adhesion over time. They are ideal for hanging towels, loofahs, bathrobes in the bathroom, or kitchen utensils like washcloths, aprons, and pot holders. They can also organize caps, keys, and umbrellas in bedrooms. The brushed finish is waterproof, anti-rust, and resistant to daily scratches and corrosion, ensuring durability and reliability in wet environments. These hooks are perfect for hanging and decorating homes, kitchens, bathrooms, hotels, and offices, helping to save space and keep rooms tidy.
