This is the travel type of the Croz soft hot water bottle. It's perfect for use at home, and it doesn't take up much space in your bag, making it convenient to carry. It's also ideal for cold対策 (cold countermeasures) while traveling or at the office. Although it's a small size, it has a good capacity and keeps you warm for a long time. The cylindrical design fits snugly against areas that tend to get cold, such as under the arm or along the arm. I have used it occasionally for one season. Heat resistance: 100°C Size: Approximately 20 x 13 x 10cm Weight: Approximately 160g Color: Black Capacity: 1.5L Made in Japan
