International Silver Company Sonic Jewelry Cleaner Never Used! 2 sonic speeds - high cleans, low rinses. Twin tanks - clean & rinse. Can also be used to clean eyeglasses, waterproof watches & other small metal items. Can use regular household liquid detergent. Thank you for visiting my closet! I will gladly accept or counter offers. Please make an offer on any interested item as I don't always reply to "Likes". Items are from a clean, smoke-free home. Happy Poshing!
