A straw for every need. Perfect for any occasion. I personally love the silicone tips for the stainless steel ones are awesome. I am not a fan of metal clicking teeth so the are perfect. Having the filter straws are perfect for your smoothie drinks with bits amity it filters them out. A must have. They are different diameters of straws for all your reusable cups with straw holes and the best thing about the stainless steel is no more children chewing the tips. It comes with handy cleaning brush with a long handles to easily clean inside the straws. The are also dishwasher safe.
