I suggest you go to the cosmetics store and ask the boss what kind of double eyelid patch your eyes are suitable for. I usually use linear. Just pull on both sides and a line comes out.

There are also 3 to 5 yuan, but it is best to stick less double eyelid stickers, because it is easy to cause drooping eyes
