Who has used Jiahekang self-heating neck protector? I think there is pepper in it.

At present, there are too many self-heating protection devices and too many fakes on the market, so you must be careful when buying them, because the ones that really generate self-heating will be tested by relevant state departments, and there should be test reports, so you must look for the genuine ones when buying them ~

Authentic self-heating products are all due to the application of tourmaline on self-heating protective equipment, which is ground and coated on protective equipment. Authentic products are not Chili powder. In order to save costs, counterfeit products only use capsaicin as raw materials, so when buying these self-heating protective products, don't covet products with low prices and uncertain quality.

Thank you. I hope it helps you ~
