These are disc magnets (12 x 2 mm) with an adhesive force of approximately 1 kg, shrink-wrapped into a square PVC cover. They can be sewn into clothing or used in wet surroundings without rusting. One sales unit contains a strip with 10 magnet pairs, which equals 20 individual magnets. If you want to use the magnets in pairs, the markings “+” and “-“ on the plastic sleeve will help you find a matching pair.
Thanks to the plastic covering, the magnets can be washed in the washing machine. To avoid damage to the machine or fabrics you should wash clothing with magnets in a laundry bag and select the delicate cycle (no spin-drying). Do not wash magnets at temperatures hotter than 80° C, as this will cause the magnets to demagnetise.
