Actually, Hanji has been around for quite some time , but I got it 7 years ago from Dr. Joseph Lee Young-jin haha I received it a long time ago . Although there is little information, I looked it up on the Internet and did it with my friend. Even when the doctor consulted, he told me in detail what parts of my eyes could and could n't . But do you feel that the line on one side is drawn less? So even after a year of doing it, it was still like that, so how could this not work? And at some point, the line got thinner and thinner, so it's just there, but I still keep thinking that I want to do it again.
