I got these Dior pony hair eyelashes from the airport. It's a limited edition kit with a pair of lashes, mascara and eyeliner that I have used up already. Not many occasions to wear falsies so this one stayed in the box til now. A freshly opened pair is usually sticky enough to last one outing without glue. But, if you want it to be fixed securely to your eyelids, that additional layer of glue is advised. Each pair of falsies can be reused 2 or 3 times, which would explain why regular users stock up jumbo boxes of them.
