The heat wine bottle caps are suitable for various glass bottles: ice wine bottles, red wine bottles, beer bottles, and fruit wine bottles. Also can be used for olive oil bottles, condiment bottles, and more. Good for bars, parties, picnics, wine cellars, homes, kitchens, etc. When applying heat to the PVC capsules, ensure to do so in a well-ventilated area and avoid direct contact with the heat source to prevent burns or accidents.
