It is large in size and has high heat retention, and the area that warms the body is also large. Why not spend this winter wrapped in the gentle warmth with YUKISEN's hot water bottle? 【Safety Design & 6-Layer Protection】 We have adopted a 6-layer explosion-proof design with high-quality heat-retaining materials and high-strength PVC. It is equipped with overheat protection, short circuit protection, overcharge prevention, over-discharge protection, overvoltage protection, and overcurrent protection. "Water and electricity" are separated, so there is no need to worry about water leakage or electrical leakage. With "pure water specifications", there is no need to worry about corrosion or strange odors. You can enjoy the winter wrapped in gentle warmth without worrying about safety. 【Soft-to-the-Touch Cover】 The rechargeable hot water bottle uses a heat-retaining pocket structure that prevents warmth from escaping, and adopts an ergonomic design that firmly wraps the entire palm. The fluffy, high-quality artificial rabbit hair used for the heat-retaining cover has a smooth and comfortable feel and blends naturally with the interior. In addition, it is resistant to pilling, and the cover can be removed and washed, so you can always use it cleanly. 【Energy Saving & Repeated Use】 Compared to conventional rechargeable hot water bottles, this product not only has a larger size, but also significantly improves efficiency. The electricity bill per charge is only about 2.5 yen, which is very economical. With an eco-design that can be used repeatedly, you can feel the warmth anytime. It provides comfortable warmth easily and can be used without worrying about the electricity bill, so the whole family can spend the winter more richly and comfortably. 【Great for Various Scenes & Winter Gifts】 The electric hot water bottle does not require preparation of hot water and is lightweight, so it can be easily carried to places where you want to warm up, such as the bedroom, living room, workplace, car, and outdoor camping. It can be easily used by women, children, and the elderly, and it is also useful as an anchor to warm the futon or as a warmer on the lap. In addition, it has a simple and high-quality design, and it looks and feels good, and it is also appreciated as a winter gift.
