I wanted to try these out, because my kids have all decided to be more conscious about the enviroment. These are quality straws and are great for water, ice tea, or soda. They are a little to narrow for a MilkShake I feel. But, most of what we use a straw for around here is the ice tea or soda. They will definitely break down faster in the enviroment and not pose a threat to wildlife like plastic straws. My kids are happy and I feel like I'm doing my best to support them in their endevors to save the earth.
