【Product Structure】 This product uses 304 stainless steel, which is healthy and hygienic. It has good sealing properties, so it won't leak even if you put it in your bag sideways when the lid is closed tightly. Although it doesn't have a handle, it has a more delicate feel than a regular coffee cup, making it the most slip-resistant. 【Aperture】 Wide-mouth type, wide enough to put ice in. 【Cold and Heat Retention】 The stainless steel double-layer structure blocks heat from the outside, allowing you to keep your warm beverages at the perfect drinking temperature. The vacuum structure prevents condensation, allowing you to enjoy cold drinks for longer. (The cold and heat retention time may vary depending on the ambient temperature and the temperature of the liquid. High summer temperatures and low winter temperatures greatly affect the cold and heat retention time.) 【Wide Range of Uses】 The cup can be used when working at the office, going to school, or traveling. Furthermore, the cup can be used not only for yourself but also as a great gift for someone else. The lid opens and closes smoothly, and it's easy to clean! Enjoy hot or iced drinks like coffee or tea easily at the office, at home, at school, or at a pub. Note: When putting it in a bag, please place the body upright. I have stored it unopened after purchase. I took it out of the box for the photos. Retail Price: ¥3,680
