I recommend Bon Pretty Nails.

This is a photo of me wearing Bon Pretty nails that I bought directly from AliExpress haha

Isn't it pretty good? I'm terrible at drawing, but it looks actually quite convincing, so I really like it hahaha.

If you buy a gel nail machine as well from Ali, you can do your nails even more cheaply!!!

If you don't care too much about quality and want something cost-effective, I recommend Bon Pretty Gel Nails.

Besides this, the syrup gel is also good!! If you're comfortable with ordering directly from overseas, give it a try.
