Update on the glass straws.
I like them more than any of the other alternatives I’ve tried (silicone and stainless steel).
They are nice to drink out of, seem fairly robust (survived being pushed through a Perspex travel mug lid for using and survived being dropped), they are relatively inexpensive and they came out of the dishwasher clean
I should add whilst they were clean, they had water marks on them but I’d expected that. Good enough that I don’t intend on handwashing them.
I’m satisfied I can see they’re are clean and I enjoyed using them so I think I’ve at last found a replacement for the plastic straws that I’m comfortable with
