Why not have thick plastic straws? If the point is to reuse them it’d be cheaper than glass and longer shelf life. Also not likely to be broken and injure someone.
Environmentalists... Always looming for a half added solution to a minor problem.
Even hard plastic straws can really damage your teeth. I have one of those plastic cups that came with its own hard straw, and if I lift it fast and mindlessly, it stabs into my front teeth painfully. Paper or the usual thin plastic is best. I can’t even imagine all the hazards connected with glass.
