What to do when it's hard to put on your favorite necklace? Use an adapter! There is nothing easier to clasp than a magnet. This high grade strong magnet is especially made for clasping necklaces and bracelets. The silver plated clasp is connected to a length of sterling silver chain with a spring clasp and ring so that you can also extend the length of your necklace 3". Once attached to your necklace you only have to get the magnets close together and they 'snap' into place! Putting on a necklace was never easier!
