I love love love my Tupkee tumbler and glass straws. No more ingesting micro plastics through plastic cups and straws exposed to hot coffee. The taste is demonstrably different, clean, fresh, non chemical tasting. I will never go back.
By the way....even the coffee shop "paper" cups have a plastic coating....think about it, while you still can. The microplastics will eventually block small capillaries and cause dementia, brain fog, etc.
