Tear the outer bag of the vacuum packaging before use. Tear open the outer bag, take out the inner bag, without kneading, and peel off the backing paper behind it, so that it can be corroded with the air, and it can heat up. There is an adhesive sticker on the back of the body warmer, which is pasted on the outer layer of the underwear and can be paved by hand. After use, gently tear it off the clothes. Shoulders, back, waist, stomach, and related joints should be attached wherever you feel cold.
The body cannot be directly attached to the skin but should be attached to the clothes through the clothes to avoid scalding. Of course, cashmere, wool, clothes, or high-grade clothes should not be pasted directly, because these fabrics are easy to be damaged by the adhesive sticker.
The body warmer can be attached to the shoulder, the back, or even the waist. It has a wide range of applications. And the price is not expensive. Usually, you can buy one for one or two yuan. It heats up very quickly. The maximum temperature can reach 63 degrees, and the average temperature is more than 50 degrees. It can last ten hours.
In cold weather, you can use it before going out, which is very convenient, just the clothes pasted on the inner layer. One thing to remember is that the product should be stored in a dry place, not in a damp place to avoid deterioration.
Note: Do not use it in the quilt, on the electric blanket, or in front of the heater. Because in these cases, the temperature will rise, which may cause low-temperature scald. Pregnant women, infants, and those who cannot take care of themselves should not use it. The skin of these people is sensitive, and the use of body warmer may cause burns.
