Joie's Rainbow Expand and Seal Bottle Toppers reseal opened wine bottles and create an airtight seal that locks in freshness to preserve wine longer. Fits most standard-sized glass bottles. Easy to use, simply insert into the bottleneck and flip the lever down to lock in freshness. Flip the lever up and remove the stopper to pour another glass. It's great for wine bottles, liquors, and spirits, coffee syrups, extra virgin olive oil, or EVOO, canola oil, and vegetable oil, plus balsamic vinegar, and to protect contents from dust and bugs for effortless outdoor entertaining, too. They're compact for easy storage in the kitchen gadget drawer or with bar supplies or other wine accessories. Made from FDA-approved, BPA-free plastic with rubber seal, Joie's Rainbow Bottle Toppers are reusable and will never rust. Hand wash in warm, soapy water as needed. Set includes 2 Bottle Toppers. Assorted colors, sorry no color choice.
