Stainless steel straws are the most durable type of reusable straw. They are thinner then glass straws so they are more likely to fit lids with straw holes. We have a large selection of mason jar lids that work with these straws. It is a little more difficult to tell if the stainless steel straws are clean so we recommend using a straw brush in addition to rinsing or washing in the dishwasher.
If you are looking for a smoothie straw we recommend the thicker 9mm diameter straw.
