These great Sewing Magnets are designed especially for sewing into fabrics. Great for purses, clasps, and many other magnetic attachments for clothing and other textiles. These magnets also work great as magnetic clasps in binders, folders and other printed materials. Sewing magnets are sold in matched pairs. An order quantity of 1 gets you two magnets.

For items that are frequently washed, we recommend the plastic cover included on this magnet, which helps protect it from moisture. For items that are infrequently washed, is the same disc magnet without the plastic cover. Machine wash cold, dry on low heat.
These sew-in magnetic snaps are super strong and perfect to add an invisible closure to your smaller bags. These are sew-in magnetic snaps that cant be seen when properly installed. Unlike most magnetic snaps, these are installed between the lining and the exterior fabric, hiding the snap from view.
For most applications you will need a magnet pair, hence, the magnets are available in pairs on a plastic strip. The plastic strip separates the magnetic pairs and makes the handling easier:
Peel off two opposite magnets from the strip and let them stick together.
Sew the lower magnet to the fabric. The top magnet broadly shields the magnetic field, so the magnets don’t get caught at the ‘foot’ of the sewing machine** during sewing.
Now sew on the top magnet as counterpart. This ensures that the magnets don’t suddenly repel each other.
