We recommend cleaning your jewelry with warm water and soap (when needed), then wipe dry with a soft cloth.
You can put a drop of any oil on the clasp to slow down rusting. If rust does occur, you can buff with a fine sandpaper. The clasps are made of metal and will rust if exposed to water or sweat.
You can also mail the bracelet back to be resized. Resizing costs $10.00-$15.00 and it can be restringed or resized.
Please be sure not to lay your magnetic jewelry near any credit or debit cards, cellphones or sensitive electronics.
