A double-walled stainless steel tumbler prevents heat transfer with a vacuum between its inner and outer walls. The foil layer covering the inner wall reflects heat back inside, contributing to excellent heat and cold retention.

Made of durable 18-8 stainless steel, the tumbler does not rust easily and the coloured powder coat finish on the surface prevents scratches. High-quality stainless steel helps to preserve the rich aroma and flavour of drinks. The smooth electro-polished interior prevents odours and stains, letting you maintain it clean and fresh.
