Preserve the flavours of your favourite red wine or save that crisp white for later with this pair of OXO expanding wine bottle stoppers. Simply press down on the flat top with stainless steel accent and the silicone seal expands to fit your bottle just right. The seal keeps air out of wine, while also preventing leaks and drips. You can then store your bottle in your refrigerator door or even lying down on a shelf. The silicone stopper expands outward within bottles to seal in freshness. The seal automatically contracts when the top is pulled up, for opening the bottle again. The compact profile suits storing bottles on the top shelf of your refrigerator. The stopper's precise fit won't slip or leak, even when storing bottles lying down. The durable stainless steel accents are an elegant touch.
