Using these bud vases is easy. First, pick your favorite flowers and trim the stems to a suitable length. Then, fill the vase with water according to its capacity (52 oz for the large vase and 16 oz for the small one), and place the flowers inside. When it comes to maintenance, clean the vase regularly with mild soap and warm water to keep its clear look. Avoid using abrasive materials as they might scratch the glass. Store the vase in a safe place when not in use to prevent it from breaking. Also, keep it away from direct heat sources as extreme temperatures can damage the hand - blown glass.
