This 2-pack set of adhesive hooks measures 11.81 x 2.76 inches and is designed for secure wall mounting without tools or damage. The strong, waterproof adhesive ensures a firm hold, capable of supporting heavy loads on shelves, racks, or organizers in kitchens, bathrooms, or other areas. To install, clean and dry the surface, peel off the backing film, and press the adhesive onto the surface. Then, place your shelf or hook onto the adhesive. The adhesives are intended for single use and work best on smooth, flat, dry surfaces. If removal is needed, heating with a hair dryer can help detach the adhesive easily. These adhesives are suitable for various wall shelf applications and are discreet once applied, providing a clean, invisible look. Ensure proper surface preparation for optimal adhesion and stability. black Plastic Waterproof heavy-duty wall adhesive strips Fits shower caddies and wall shelves Tool-free, wall-safe installation
