What if you could turn any cup, anywhere, any day into a straw cup? Great news – you can! Made from 100% European-grade platinum silicone, the GoSili Silicone Straw Lid stretches over a WIDE variety of cups and glasses. When the silicone lid is stretched over a cup, the suction keeps the lid in place making your new straw cup virtually spill resistant. Use it at a restaurant, keep the bugs out of your drink while sitting at the campfire, use it poolside or on the boat – the list goes on. Never be without a lid or straw again! The included reusable silicone straws won’t melt in your drink like a paper straw or hurt your teeth like a stainless-steel straw. GoSili reusable straws are translucent, so you can easily make sure your straw is clean! Whether you are out at a restaurant or enjoying a picnic in the park with your family – don’t forget your universal lid and straw. It will meet your needs, no matter where your day takes you.
