To use, melt small pieces of wax in a heated spoon until liquid. Pour the melted wax onto your desired area. Press the seal stamp into the hot wax and hold for about 5 to 15 seconds until it cools and hardens. Carefully remove the stamp once the wax is solid. The brass surface may develop dark oxidation over time, which can be cleaned with a cloth and a small amount of vinegar. This seal stamp is suitable for decorating gift packaging, envelopes, parcels, invitations, wine bottles, and more. It can also be used on cards, scrapbooks, glass, plastic, and wood.
