HIC Bar's Expanding Bottle Stoppers reseal bottles to create an airtight, leak-proof seal. Easy to use, they fit most standard-sized glass bottles. Simply insert the stem into the bottleneck and flip the lever down. Flip the lever up and extract the stopper to pour another glass. They're great for wine, champagne, spirits, coffee syrups, EVOO, vinegar, soda, mineral water, and more. They're compact for easy storage with bar supplies or other wine accessories. Made from stainless steel with BPA-free polypropylene, HIC Bar's Expanding Bottle Stoppers are reusable and dishwasher safe for easy cleanup.
