For strong hold and unique design, shop our selection of magnetic clasps. Magnetic clasps are held together by very strong magnets. They are easy to hook together because the magnets are attracted to each other but they won't come apart easily because the magnets are so strong. This ensures you will have beautiful, functional designs that will stay secure. Magnetic clasps come in a variety of shapes, sizes, designs and finishes, so you are sure to find something to fit your needs! Magnetic clasps should not be worn with a pacemaker.
