Do you prefer your water bottle to be made of metal, plastic, glass, or something else? Straw or no straw? How big would you want it? Should the bottle taper down in the bottom, or do you think the sided should stay vertical? Are any of you one of the few people who would like that weird rectangular bottle? Or maybe one of those squishy fold up ones for travel? No handle, flip up handle, mug style handle, or little loop?

Yeah, I dunno. I thought it it was just mould, it would wash off. I’ve taken some pretty harsh chemicals and scrubbers and they don’t give any. But the black dots that form on the rubber gaskets when they’re exposed to moisture weirds me out. If it’s not mould, even discolouration would be strange.
