LADYBUGS WOOD BURNED WINE BOTTLE STOPPER SET OF 3 These wine corks are standard size and topped with a natural wood button. I hand draw the image into the cork toppers, apply some heat and love, then finished with a durable, food-safe polyurethane coat. Your stoppers should be handwashed as needed with hot soapy water and dried. Do not soak water. Not safe for microwave or dishwasher. Store in a cool, dry place out of direct sunlight.
