Good idea, but what are you going to use instead? As plastic ones are out, that only leaves glass and perhaps bamboo straws. I know they exist as I've seen them (but I can't say I've seen a glass one in decades).

Unfortunately, from my recollection, glass straws are inconvenient and can be dangerous if broken.

Frankly, I reckon it's hopeless, between nano plastics and PFAS I can't possibly conceive how I can effectively eliminate them from my life.
