Leak-proof, Double-Wall vacuum insulated bottle with lid that doubles as a cup
Keeps liquids hot for up to 40 hours, cold for up to 35 hours, or iced for up to 6 days
Lifetime
Dishwasher safe
Made with 18/8 stainless steel, so it won't rust and is naturally BPA-free
i find it very hard for the dishwasher to clean long bottles like this. Any tips?
