★Instant purchase OK★ This is an insulated mug made by Klean Kanteen. It has a slide-top cap for easy use, and is made of stainless steel, so it's easy to clean and hygienic. The calm, high-quality blue color and timeless design are also attractive★ It's durable even if dropped quite violently★ ↓ I used it at work (with mountain work) for about six months, and the only scratch is on the bottom, as shown in photo 7. The body is undamaged and very durable★★★ By the way, after use, I soaked it in bleach, so there are no stains like tea stains (see photo 6). Please use it to prevent heatstroke and for your drink-carrying and money-saving strategy during the hot season★ - Brand: Klean Kanteen - Color: Purple - Type: Insulated mug - Cap: Slide-top cap - Material: Stainless steel Thank you for looking.
