For more than 50 years, Rotpunkt products have been the epitome of high-quality and long-lasting insulating cans with the best warm or cold-holding function.This timeless copy is a true highlight of form and color. The personal note is underlined by the unusual and dynamic design of the jug.This high-quality thermos can keep coffee, tea, juice or iced tea pleasantly cool or long warm. The mouth-blown glass piston is made of double-walled insulating rosalinglas. This enables an optimal and long-lasting insulation through vacuum and a special silver coating between the two glass pistons.Thus, a keep-warm time of approx. 24 h and a cold-hold time of up to 36 h is achieved when the jug is filled. High-quality sealing rings as well as the reliable screw cap enable a long and reliable use.This text is machine translated.
