Using these pasties is easy. Just peel off the backing and stick them on your skin. Make sure the skin is clean and dry for a better adhesive effect. When wearing the chain, you can clip it on in different styles to match your outfit. For storage, keep them in a cool and dry place. After each use, you can clean them gently with a soft cloth. Be careful not to pull the chain too hard to avoid damage. And don't forget, these pasties are reusable, so take good care of them for multiple uses.
