Copper AZUMA DOUBLOON 5-piece set Copper Mug (7.5cm x 9cm) These copper mugs boast excellent thermal conductivity and antibacterial properties. They're perfect for iced coffee, beer, and other drinks, making them a great addition to camping trips and barbecues. They also evoke a retro atmosphere, similar to the copper mugs used at Hoshino Coffee and Ueshima Coffee, where they serve ice-cold iced coffee. The mugs develop an antique-like patina with each use, offering the enjoyment of "growing" them over time. These are new, unused items that have been stored at home. They come with a dedicated wooden box. The logo on the mug is a sticker and can be removed. The wooden box will be wrapped in cushioning material for shipping. Please feel free to inquire about a discount.
