For me, it only stays for like 2-3 days... I watched the tutorial and a lot of youtube videos and did exactly the same way but it still doesn't stay any longer. It looks really good for the first day but after 1 or 2 showers, it just... doesn't seem to stick with my eyelashes anymore. I even try not to wet my face during the shower but still... :( And I think the biggest advantage of this product was that it doesn't hurt your real eyelashes, but after several uses, I feel like my lashes are getting weak and falling off. I really wanted to like this product so I've tried 11 packs of different lashes here but now I give up It just doesn't work for me
