While one individual plastic straw doesn’t create an environmental disaster, it’s the scale that's beyond our wildest imagination that creates an issue. Because you can wash and reuse glass straws, you won’t be contributing to the waste that comes with disposable plastic sippers.
Borosilicate glass straws are non-porous and hypo-allergenic. So even if there was a harmful ingredient in your glass straw, it would never leach into your beverage. Borosilicate has super durability, being more break-resistant than other glass.
It takes more than you think to break these awesome straws!
