Now there is.

Meet our new Polar Series vacuum insulated tumbler. Powered by next-gen high-vacuum tech, it locks in temperatures above 65°C for six full hours. Not just lab-perfect—production-line consistent.

Weight? Just 280g. That’s 18% lighter than our previous gen. One sourcing director from North America put it this way: “This is the least stainless-steel-feeling stainless steel tumbler I’ve ever held.”

Samples ready. First bulk order lead time: 45 days.

Prev : Cold brew tumblers are trickier than they look.

Next : Last year, we started OEM production for three Japanese brands. This year, two renewed. The third doubled their volume.
