This straw is 9mm diameter, slightly wider than a regular straw, so is suitable for all liquids including smoothies.  Made from 304 grade stainless steel that has good resistance to rusting.  Our straws have zero packaging.

Price is for one straw.

For keeping your straw clean, you need a small brush with a long thin handle such as our straw cleaning brush >

Stainless steel straws have the benefit of not breaking like glass straws and not degrading like bamboo straws. However, you do need to be careful when bringing a metal straw into your mouth as you can hit your teeth or lips and cause a small injury.  The rounded end on these straws helps eliminate that potential harm.  Even if no harm is caused, some people simply do not like the 'sharp' feel of the end of stainless steel straws. 


  • Before using, always wash straw inside throughly with a straw cleaning brush.
  • Not suitable for children due to the rigid pipe and ends which may injure. Take care also with people with mobility difficulties.
  • A stainless steel straw is not a toy! Do not let any children use unsupervised. Do not allow children to walk or run with the stainless steel straw.
  • Anyone given a straw should be taught not to bite down on the straw as it may hurt their teeth or mouth. 
  • Do not walk or run with the straw.

Available here are soft, flexible silicone straws for children.


9mm diameter, 21.6cm length. Please note that these straws do not fit in the Ball Mason Daisy Lids.

Reusable stainless steel straws help you reduce throw away waste of plastic straws and keep plastic straws from entering our rivers and oceans.

bought as a gift

I bought this as a gift for someone to introduce them to low waste living. I do note this is made in china, and not a lot of info is given on whether it is made in a responsible factory.

These straws are beautiful. High quality. I like the rounded lip. Our kids love using them, too. The cleaning brush is good.
