Using your Vietri Regalia wine glass is easy. Just pour your favorite wine into it and enjoy. When it comes to cleaning, always hand wash it to keep the 14 - karat gold hand - painted design looking its best. Avoid using abrasive cleaners or putting it in the dishwasher, as this can damage the glass and the gold paint. Also, be gentle when handling it, as it is made of delicate mouth - blown glass. Store it in a safe place, away from other hard objects that could scratch or break it.
