The straws are made of borosilicate, which is typically used in the laboratory. It is shatter resistant, and on the Mohs hardness scale (where diamonds are 10 and chalk 1), borosilicate glass is rated at 7.5 points. The regular glass is only 5.5.
It is dishwasher safe and can be cleaned with a brush (included).

Really amazing straws! Durable, beautiful, and for the price! Also, love the environmental footprint as they are Czech made. I can only recommend <3

These glass straws are just amazing. Love the price. They are very strong, ideally long and wide – they even fit a small can. Simply perfection itself, plus a beautiful minimalist design.
