Waterproof Sewing Magnets

The thin neodymium magnet surrounding thin steel cups can be used as magnetic button, also known as sew-in (sewing) magnets, the kind of strong waterproof magnets. Usually the outside also sealed a layer of PVC waterproof film. PVC waterproof film can protect the magnet from corrosion. The plastic layer also provides something to sew on to keep the magnet in place. If you use it in a leather bag that doesn't get wet, use sew in magnet without PVC. Our PVC sew in magnets can be washable, they are widely used in textile as waterproof magnetic buttons.

Sewing PVC magnets with a sewing machine

For the application of magnetic buttons, the pvc magnet needs to be paired sewn into textile, make sure  the PVC sewing magnets + and - are attached to each other.


Remove the two opposite PVC sew-in magnets from the strip.


Sew one of the sew-in magnets onto the fabric. The other magnet is temporarily placed away from the metal object.

Now sew on another pvc magnet with the opposite pole. Make sure the magnets don't repel each other.


Many parts of the machine are magnetic, so it is not easy to sew strong sew-in magnets onto fabric with a sewing machine. If available, we recommend sewing magnets to the fabric by hand.
