The double-walled 1.9-litre Classic Vacuum Insulated Flask has had a makeover and is now more durable, provides a smoother pour, has an improved handle for a better grip and can be washed in the dishwasher while able to hold an entire pot of coffee and keep it hot for 45 hours. This flask can also keep liquids cold for 2 days or iced for 8 days. It is still fully leak proof, made from naturally BPA-free stainless steel with a rust-proof finish and comes with an insulated lid that doubles as a cup. Built to last a lifetime. 1L. Boxed.
