I bought a 4-pk of glass straws for €5 and they are awesome. The rounded edge feels smooth on the tongue/lips and drinks taste better through glass than metal.
The ones I’ve handled and bought are more robust than most other glassware. They can break if dropped on hard floor, but that’s normal for anything out of glass.
Can confirm, they are durable. I broke some similarly sized vaporizer glassware the other day. Yet these straws have held up being thrown around in a sink full of dirty dishes.
Of the 4, only one has gotten scratched to the point that I recycled it (manufacturing error methinks), but the other 3 are holding up well. I’ve had them for a little over a year.
