Discover the RETUMBLER-Grand Canyon thermo mug! With an impressive capacity of 1200 ml, it is the ideal companion for long periods of thirst. The powder-coated thermo mug is made from recycled stainless steel, recycled AS, and PP plastics. Thanks to the double-walled copper vacuum insulation, the drink stays cold for up to 32 hours or hot for up to 9 hours. The mug is particularly suitable for summer refreshments. Prefer it ice-cold? Thanks to the generous opening, ice cubes can be easily added, which stay frozen for up to 48 hours due to the excellent insulation of the mug.
