What if you could turn any cup, anywhere into a straw cup? Great news – you can! Made from 100% European-grade platinum silicone, this 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. This lid + straw combo pack comes with its own travel tin so you can take it with you and reduce your plastic footprint. 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 straw is 8 inches tall with an opening of 0.6 centimeters, flexible, and 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! On behalf of our planet, thank you for making the choice to waste less, and GoSili.
