What about the pair?

To put it simply, Shuang Feiren Shuangshui is made in pairs. Because the trademark of Shuangshui has been registered by domestic manufacturers, products made in Hong Kong cannot be sold in China. So in a regular drugstore, you can only buy double water. Actually, it's not bad for a threesome to have a cold water. It's similar in Hong Kong, and the price is much cheaper. The most important thing is that Shuang Feiren won't have fakes when it comes to toner, unlike the time when it was bought in Hongkong, many of them were fakes.
