Just stick it to your back or waist! Easy-to-open U-shaped cut. Stable warmth lasts for 14 hours. Why is the maximum and average temperature reversed between the stick-on and non-stick types? The temperature curve decreases differently for the stick-on and non-stick types, resulting in a higher average for the stick-on type. The stick-on type is designed to be used on clothing, set for morning to night, while the non-stick type is designed to last as long as possible. The stick-on type has an adhesive sheet that can be attached to clothing. The adhesive is selected to minimize residue on clothes when removed, not to be too strong to damage clothing, and to ensure it does not peel off due to the weight of the warmer during use. The texture of the stick-on and non-stick types is slightly different. This is due to the difference in surface processing of the non-woven fabric; the non-stick type, which is held in hand, uses a harder material to prevent fluffing, while the stick-on type, which is not held, prioritizes softness over strength.
