This is a set of 4 pore-cleansing packs! I'm selling them because I don't use them. Of course, the individual packaging is unopened, so the contents are clean. There are no paper instructions. This is a sale of the product itself only. The usage instructions are printed on the back, so please refer to them when using. I hope someone who wants to try them will use them. If you have any questions, please feel free to ask in the comments section.
