I recommend two kinds of double eyelid stickers. One is a double eyelid sticker sold by Watsons, and the other is a Japanese brand. It's made of 3M adhesive tape, which is very sticky. There are several kinds (daily use, night use, ultra-fine and ultra-transparent), but they are a little expensive. I used a special 2mm cosmetic patch made in 32 yuan, 40 yuan. There is also a kind of 3M home tape, which costs about ten yuan, but you have to cut it yourself.
In fact, the glue is almost the same, and it is still a question of proficiency. Too much glue is easy to dry and turn white, and too little glue can't stick or stick piece by piece. Honey, you can practice more.
The double eyelid fiber is also good. This is very similar to a double eyelid patch. It's the same as a thread. Both ends are wrapped with sticks. Just find a suitable place to paste it and drag the sticks off the sides. But this is also more expensive, and it is not sold in many places. . . I bought it online, too.
But optical fiber is rarely used now, in order to save money. I usually buy a few dollars of stickers, put them before going to bed, take them off the next day and stick them with glue. It looks troublesome, but it's natural.
