This is a hard-to-find Dverg double-wall tumbler in amber, 210ml. It sold out immediately online, and the official website stated that the limited sales at a September event were the last restock and there would be no further production. If you're interested, don't miss this chance. The double-wall construction keeps hot drinks warm and cold drinks cold, while also preventing condensation. Made of heat-resistant glass, it eliminates the metallic taste sometimes associated with stainless steel tumblers. It's the perfect size for hot coffee, iced coffee, or enjoying liquor on the rocks.
