A small hot water bottle that brings comfort when your body feels cold.
Compact and easy to carry, it’s perfect not only in bed but also for warming your lap, easing discomfort, or bringing gentle warmth during work or reading time.

The cover is carefully crafted with two layers of natural materials:
a soft outer layer of cotton blended with cashmere for insulation and warmth,
and an inner layer made from a biodegradable mix of regenerated cellulose fiber and wool.
Together, they hold heat longer and offer a natural, comforting touch.

A new color, Fog Gray, is now available — designed with a slightly longer top opening for a refined look.
Both Natural and Fog Gray blend beautifully into your everyday life.

To let more people experience the quality and craftsmanship, we are offering this item at a special online-only price — perfect for daily use, winter gifts, or cozy camping moments.
