My water cup is just a grocery store special, stainless steel, double insulated. Tight lid with a silicone gasket. Rubber base. I've had it for years; the original coating peeled off, but still functional and works for me.
I spotted something similar on Amazon for $12 https://www.amazon.com/WETOWETO-Tumbler-Stainless-Insulated-Spill-Proof/dp/B0BJVFFCR4
