We made the world's first Carbon fiber reusable drinking straws. After trying to switch from disposable drinking straws to a reusable straw, we found several metal types that had several major issues, like the metal aftertaste, the feeling of the metal in the mouth and that the fact that they could bend pretty easily. Then we tried Eco straws that we found that they were extremely expensive to use in the long run.
Carbon fiber is the perfect material for the job! It's anti-bacterial, won't bend or break no matter how hard you try, extremely lightweight (0.25oz/7gr), no aftertaste, dishwasher safe, and feels like any other plastic straw in the mouth.
