Personally, I have always recommended cosmay or opera, especially Cosmay is pure natural, which has no irritation to eyes and no smudge. Clear water is easy to wash off, recommended, but the price is a little more expensive than opera. Maybelline's endless slender doll was specially bought to try, but it didn't say that it could pull the eyelashes very long, the workmanship was too rough, and the grade was questionable.
