The disc or square neodymium magnets sealed in PVC film are best magnetic attachments for fabrics,which known as neodymium sewing magnets(also called sew in magnets)
Each magnet is coated in a soft waterproof PVC film for waterproof and corrosion resistant. To ensure that the neodymium sewing(sew-in) magnets have long-lasting performance and reliability, the plastic film is made with a wide sewing boundary, which is convenient for sewing onto clothes and fabrics. The waterproof sewing(sew-in) magnets are designed for clothes, curtains, pullovers, bedspreads, cushions and other items, which are regularly cleaned or dry cleaned. Neodymium sewing magnets also work well as magnetic clasps in binders, folders and other printed materials.
