Connect as many as you want and sip away! Made from 100% nontoxic platinum silicone, these reusable silicone straws are soft and flexible and easily interlock for some good sipping fun. A GoSili reusable silicone straw won't melt in your drink like a paper straw or hurt your pearly whites like a stainless-steel straw. These straws are the perfect alternative to all of those single-use plastic straws that end up in our landfills and pollute our waters! As an added bonus, the built in stopper on the base of every SiliStraw helps prevent the straw from being pulled out of lids - you're welcome parents. GoSili straws are designed with maximum durability in mind, while also being easy to clean! Because our reusable straws are translucent, you can easily see when the straws are clean. They are dishwasher safe, can be washed by hand (no brush required!), and can even be boiled to sterilize. To wash the straw by hand, place a drop of soap in the opening of the straw. Roll the straw between two fingers and rinse until the water runs clear. On behalf of our planet, thank you for making the choice to waste less, and GoSili.
