The self-made tutorial for cold stickers is as follows:

1、? First of all, prepare a sealed bag, which is relatively clean and hygienic, and it is best to use it for the first time.

2、? This sealed bag, we cut it into the size we think is suitable with scissors.

3. A very, very ordinary wet towel. We tear it apart and fold it.

4. As shown in the figure, the size is just right. We put the wet wipes in a small sealed bag.

5. You can add some cartoon patterns around by sticking double-sided tape, which will be more cartoon.

6. A simple version that is very comfortable after the double-sided tape is fixed. After cold pasting, it can also be put in the refrigerator and pasted after going out.

Cold adhesion principle:

Cold paste can usually play a role in cooling and reducing fever during use. The main components are backing, gel layer and anti-sticking layer. There will be a lot of water in the course, which can play a role of temperature in the process of water evaporation, thus playing a role in cooling down.

It also contains ingredients such as mint and borneol, which can stimulate the skin, make it feel cold and moist, and help reduce fever.

Cool stickers generally need external use. Different brands of cool stickers or different environmental temperatures during use will have certain deviations in the maintenance effect and time of cool stickers. If the ambient temperature is relatively high, the general curing time will be shorter, and if the ambient temperature is relatively low, the curing time will be longer.
