This is an anti-static ring. It prevents the annoying shocks of static electricity, making it recommended for the dry winter months. I have carefully stored it in a dark place since I obtained it. Only those who understand that it has been stored at home, please purchase. When shipping, I will package it in a bag, etc., and take measures to prevent water leakage. I try to ship as quickly as possible, but due to work, it may take a few days to ship, so please understand. Type...Rubber band Title...Anti-static ring
