Description[Material] - The wine bottle cap is made of PVC material, which is highly corrosion-resistant, waterproof and heat-insulating, and can well protect bottle stoppers and maintain the freshness of wine or other beverages.[Easy to Use] - It is very convenient to use, just cover the bottle, insert the heat shrink caps, and then use a heat shrink machine to shrink it. If you don't have a professional machine, you can also use a hair dryer or boiling water to shrink.[Good Sealing] - The shrink cap can completely seal the bottle mouth, not easy to leak, and effectively isolate external air. If you have an opened bottle of red wine but haven’t finished it, you can seal the bottle with our heat shrink cap to protect the original flavor of the wine.
