Jewelry care will ensure your handmade jewelry lasts for a very long time. Jewelry tarnishes easily, even exposure to air will cause sterling silver will tarnish over time. These chemically treated polishing clothes will gently wipe away oil, dirt, and remove tarnish from your jewelry. These cloths can be used over and over again for years even after they turn black from tarnish. *Tip* When you are not planning on wearing your jewelry for a long time, you can store it in a jewelry zip-lock bag to slow the tarnishing process.
