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 aren't frequently washed, such as purses, wool or leather items, the strength of these magnets is slightly better without a plastic cover.  For items that are frequently washed, our SWP-L is the same magnet with a protective cover.  Machine wash cold, dry on low heat.

Choose your size based on the thickness of all material layers between the magnets in your application.  Aim for a pull force between 1 and 3 pounds for a nice feel, though the desired strength does depend on the application.  This magnet is great for total material thicknesses of 1/16" to 1/4".

The table below shows the expected strength when used with a variety of materials.  The Pull Force assumes the magnets are separated by two layers of the fabric.
