This base-metal Mag-Lok magnetic clasp features a silver finish and extra-strong magnets, ensuring your jewelry designs remain fastened. The magnets self-align, making it easy to put on and take off, ideal for customers who have difficulty using traditional clasps. No glue is used in the construction of this clasp. To help prevent loss, care should be taken to ensure that the jewelry piece is not heavier than the clasp can support. This clasp is plated with fine silver to ensure a bright white color and to help protect against tarnish.
