There is no knife for double eyelids now! That sounds horrible! It is also the kind that is best not to press. If it is not firm, it will be easy to open! It is best to use Korean three-point positioning, and the effect is good! That's what I do. I can keep it for life! Mudanjiang is also a beautiful god. After all, her family specializes in double eyelids. Their dean has worked for more than 20 years, and her staff are sure! Prices range from 1000 to more than 3000! Not bad. It should be acceptable. Other places are much more expensive than here! In Harbin, the qualification price of Meishen is above 10000, so I still choose to go home and do it! If you want to do it, you'd better go and see for yourself and consult! I'll tell you the address, and you can have a look for yourself when you are free! Meishen has now moved to Room 208, Dongsheng Building at the intersection of Dongyi Road and Peony Street! I hope my answer can help you!
