I bought these because I have one monolid and one creased lid. This was the first brand I tried. I selected this one because it has the most reviews.These come with several sheets in a small plastic box, a V shaped applicator, and instructions in English.It was easy to figure out using the instructions. After two or three tries I was coordinated enough to apply it.They work and are very sticky. I would apply before makeup for maximum adhesion. You can apply after makeup or after. If I applied before makeup and immediately needed to remove it I couldn't peel it off unless using makeup remover. However, at the end of the day I could rub it off.After a couple of days with the tape my eyelid stayed creased without the tape! However, it went away. I haven't been able to get the crease to stay again. It could be because I am not consistently using it.Sometimes you can see it but it is not a big deal with makeup.My mom just got back from a Korean store in Atlanta where she bought me several other brands of double eyelid tape. After comparison I think I am going to stick with the other brands because of one thing-- the duwop brand has pointy ends. The end of the tape closest to my inner eye would poke the skin and it hurt unless applied just right. All these other brands have rounded ends. However, as far everything else goes Duwop is much better- convenient box, more sheets, the V shaped applicator, and ease of removing from sheet. I really prefer the V shaped applicator over the pronged ones. The sheet is cut so you can remove it from the sheet without touching the adhesive on the tape.Also, I don't know what the difference is but Duwop is thinner than the other brands.
