1. Extra-strong load-bearing. The suction cup hooks heavy duty can hold a maximum load of 3kg. The suction cups adhere to smooth walls sturdily and stably. Perfect for mounting on shower walls, mirrors, and tile walls or doors for hanging towels, loofahs, sponges, bathrobes, kitchen utensils, Christmas wreaths, and more. 2. Easy to install. No tools, no drilling, no screws, no holes. Simply lift, push, and lock. The wreath hanger made of high-strength clear plastic PET material and high-tech locking technology will not yellow over time or reduce adhesion. 3. Removable and reusable. No trace. With a powerful locking suction cup design, you can remove the shower hooks by simply releasing the lock, clean the suction cup with warm water, and dry it for re-installation in another location. 4. Widely use. The suction hooks can stick firmly to windows, mirrors, glass, metal, or any other non-porous surface. (NOTE: The suction cups with hooks are not 3M sticky hooks; they will not stick to soiled or painted walls, carpeted walls, or wallpaper surfaces.) 5. Heavy-duty suction cup. Wreath suction cups with lever lock technology provide ultra-strong hold. Heavy-duty polycarbonate material and lever lock technology ensure that each suction cup hook can be firmly attached.
