Takes a while to get used to, but holds the fold a lot better than normal tapes.
Less finicky than glue.
This particular brand doesn't come off even if you tend to sleep on your face at night.
Two or three packs might be enough for people with thin eyelids.
Certainly takes longer (I'm still going, 2-3 months on) for people with fatty lids.
The tool it comes with makes it a lot easier to use than the conventional forks.
Won't suggest following the method of application that comes in the instructions, however, as I found that it was harder that way and most of the time, gave me uneven folds.
Easiest to just use a rolling motion from the inner corner of the eye, out.
The product is pretty expensive and a lot will go to waste when you first start using it, but I would say it's still worth it.
Gives a very defined crease, doesn't come off throughout the day (provided you stick it on properly and on clean lids) and helps maintain the crease in the long term.
