New, unused double-walled titanium lock cup "Kasumi" made by craftsmen in Tsubame City, Niigata Prefecture, with a wooden box. Thanks to its double-walled titanium construction, it achieves high cold and heat retention, preventing the heat of your hand from transferring to the drink, making it difficult for ice to melt and keeping hot drinks from cooling down quickly. It also prevents condensation even when ice is added and doesn't alter the taste of the drink, offering extremely high practicality. If you are looking for one, please consider it. m(_ _)m - Color: Double-walled titanium - Material: Metal - Accessories: Wooden box - Design: Smooth curved shape - Size: Drinking mouth approx. 7cm x height approx. 8.5cm (250ml) - Inner finish: Smooth and glossy Thank you for viewing. ※Please note※ Due to home storage, there may be overall damage such as scratches, scuffs, and discoloration.
