Product diameter 4cm, height 1.5cm Rust-proof: Shower curtain magnets are 360 degrees covered with high-quality silicone. The sealed cover can completely isolate the internal magnets from air and water to avoid corrosion, ensuring long-term use and durability. Anti-collision and noise reduction: The soft silicone shell of the curtain weight can act as a protective layer to prevent the internal magnets from breaking into pieces when accidentally dropped, while other magnets are easily broken due to hard covers. The silicone cover can also act as a dampening layer to reduce the sound when our curtain weights hit the bathtub, while other magnets may make a lot of disturbing noise. Wide range of uses: These magnets can be used not only as shower curtain weights, but also as curtain weights to prevent curtains from blowing away; as canvas weights to hold canvases in place; as refrigerator magnets to fix memos and shopping lists; as whiteboard magnets to stick notes and pictures.
