Stainless shower curtain magnets are 360° covered with premium silicone. The hermetic silicone cover can completely isolate the magnets inside from air and water to avoid corrosion and ensure long-term use and durability STRONG Magnets The magnetism of our curtain magnets is twice as strong as others on the market. Even for the very thick fabric or plastic curtain under running water, our shower curtain magnets will attract each other tightly and will not slide down Proper Weight Each pair of magnetic curtain weights weighs about 3.6 oz, which is twice as much as most curtain weights on the market. According to the user, it is the most suitable weight to keep the shower curtain liner in place and prevent it from blowing away Anti-collision and Noise Reduction The soft silicone covers on the curtain weights can act as protective layers to prevent the magnets inside from breaking when accidentally falling, while others break easily due to the hard glass cover. The silicone covers can also be noise-reducing layers to dampen the sound when the curtain weights hit the bathtub, while others can cause loud and annoying noises. Wide range of uses These magnets can be used not only as shower curtain magnets, but also as window curtain magnets to prevent the window curtain from blowing away, as tablecloth weights to keep the tablecloth in place, as refrigerator magnets to attach notes and shopping lists, and as whiteboard magnets to attach notes and pictures.
