hmm glass bottles here have a metal cap, not a plastic one...also plastic bottles have plastic cap so it will also ruin the water but you have the full bottle too
as for metal, avoid alluminium, that drops it and you drink it
Next time I'll give a look, but I'm pretty sure I seen rust on a cap of a bottle I kept at home in the inner part
At least we in Europe have a plastic seal part in these. But anyway, everything today is filled with microplastic - it is almost unavoidable. Time to think about our (plastic-) consumerism
That's true, we use too much plastic and I see it also from how much plastic garbage I produce, everything is inside plastic
