Strong Magnets & Heavy Enough: The magnetic force of these shower curtain magnets is so strong that you can't simply pull them apart; you have to slide one off the other. Once attached to the curtain, they won't slip or fall off, regardless of splashing water or wind. Additional metal inside the silicone casing makes them heavy enough to hold the curtain securely in place. Never Rust or Stain Your Curtain: The full silicone coating protects the magnets inside from chemical reactions with water and air, preventing rust. Unlike other curtain weights with exposed magnets that can cause rust stains on your beautiful curtain, ours won't. Never Break or Fall Apart: These curtain weights are made of high-quality silicone, stainless steel, and strong magnets. Unlike other curtain magnets, our shower curtain magnets can break after impact with the tub due to cheap hard plastic, injuring your feet, or fall apart due to poor adhesive. Safe for Children and Dogs: These shower curtain weights are large enough; Don't worry about your child or dog accidentally swallowing these magnets. The best solution for keeping curtains from sticking: metal clips or exposed curtain magnets can rust, and plastic clips won't work. Our silicone-coated magnets are your best solution for preventing annoying shower curtains from sticking to your legs, tablecloths from flapping in the wind, and window curtains and outdoor curtains from billowing.
