Klean Kanteen Recycled Stainless Steel Straws
Klean Kanteen
Recycled Stainless Steel Straws
The soft silicone tip is the point of this one: it takes the hard edge off a steel straw for kids and for anyone who dislikes metal on their teeth, and it pops off so you can actually clean it. A 2 rather than a 1 because of the silicone tip and because the brand does not say what the packaging or the brush bristles are made of.
Two-piece straws in certified 90% post-consumer recycled 18/8 stainless steel with a removable food-grade silicone flex tip, from a B Corp that also carries Climate Neutral certification and a lifetime limited warranty.

What's inside
The straw tube is 18/8 stainless steel certified as 90% post-consumer recycled, an inert metal that leaches nothing and sheds no microplastics, with an electropolished interior that cleans easily. The soft tip is removable food-grade silicone. Silicone is not a petroleum plastic and is not a microplastic source the way plastic is, though as a polymer it can release trace particles or siloxanes, more so with heat and age. Whether silicone forms microplastics is still an open question.

About Klean Kanteen
Klean Kanteen is a family- and employee-owned California company founded in 2004 in Chico that helped start the reusable stainless steel bottle category. It makes water bottles, insulated tumblers, cups, food canisters, and steel straws.
It is a certified B Corp and carries the Climate Label for measured and offset carbon, both confirmed in their registries, and it is a longtime member of 1% for the Planet. The bottle bodies are stainless steel, but many caps and lids contain plastic, so it is low-plastic rather than fully plastic-free unless you choose an all-stainless cap.
