I bought a 12 paper towel from the supermarket. My anus has been itching since I used it. At first I thought it was caused by dirty underwear. It's no use wearing Piyanping all the time. Later, when the tissue was used up, I changed to another brand, and it was okay. Some time ago my wife went to the supermarket and bought another one. As a result, my anus began to itch again during this time. I remember I used this brand the year before last. When I stopped using another paper towel, my itching got better. I seriously doubt what chemicals have been added to this paper towel. Really want to find a place to test why such a big brand is like this. Paper towels are bought in big supermarkets.
