Forget about burns and accidents, and just be enveloped in warmth. 【Gentle towel fabric, a comfort you'll want to touch every day!】The cover of the YUSIDO hot water bottle uses high-quality pile fabric, the same as the towels used for babies' skin! It's fluffy and soft, absorbs sweat and moisture while keeping you feeling dry.

Furthermore, the soft cushioning of the towel fabric provides zero stress even when hugged for a long time. It's like being wrapped in a "clean hotel towel." It can also be washed, so you can always keep it clean, and you'll want to use it every day. It has a simple design that blends in with any interior♪
