Rust-proof: The shower curtain magnets are wrapped in high-quality silicone 360° all around. The sealed silicone layer completely isolates the internal magnets from air and water, preventing corrosion and ensuring long-lasting use and durability. Strong magnetic attraction: Our shower curtain magnets have twice the magnetic force of other products on the market. Even heavy fabric/plastic shower curtains stay firmly in place under running water and do not slip. Moderate weight: Each pair of magnetic shower curtain weights weighs approximately 3.6 ounces (about 100 grams), twice as much as most shower curtain weights on the market. According to user feedback, this is the optimal weight to secure the shower curtain and prevent it from swaying in the wind. Impact-resistant and noise-reducing: The soft silicone shell of the shower curtain weights protects against the internal magnets breaking in case of an accidental fall, while other products have hard shells that are easily damaged. The silicone sleeve also acts as a cushioning layer, reducing the noise generated when the shower curtain weights hit the bathtub, which can be quite noisy with other types of shower curtain weights. These magnets have a variety of uses: they can be used not only as weights for shower curtains and curtain weights to prevent curtains from being blown away by the wind; as tablecloth weights to keep tablecloths in place; as refrigerator magnets to add notes and shopping lists; and as whiteboard stickers to add notes and pictures.
