This is a BAR TIMES STORE original product that uses lacquer, a traditional Japanese craft, on a popular bar tool, using vivid vermilion and deep glossy jet black colors. The lacquer used is Kiso lacquerware from Nagano Prefecture, a lacquerware production area with a history of over 400 years, and each item is handmade by craftsmen. It doesn't slip when you pick it up, and it doesn't transfer body heat to things like shakers, so it's the perfect item for delicate cocktail making.delicately and more deliciously, with the least amount of foreign body sensation when the glass touches your lips.
