Stainless Steel Polar Camel Tumbler features double-wall vacuum insulation with a clear lid. It is 2X heat & cold resistant compared to a normal travel mug and is BPA and lead free. Polar Camels are made from 18/8 gauge stainless steel (18% chromium/8% nickel – also known as Type 304 Food Grade.)
Tumblers may have the Polar Camel brand stamped on the bottom cap of the cup. Standard lids have the Polar Camel lid shown in the listing photo. Upgraded sliding lids do not have any branding on them.
