This stainless steel straw is 6mm diameter so is suitable for liquids such as water, juice and tea. Same diameter as the black plastic straws many pubs use for softdrinks and spirits/

Made from 304 grade stainless steel that has good resistance to rusting. 

Our straws have zero packaging.

Price is for one straw.

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. 


  • Made from high quality food grade stainless steel #304.
  • Suitable for cold drinks - not recommended for hot temperatures.
  • Lightweight.


  • 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.
