Leo Full Lash False Lashes

I absolutely love these lashes! They look stunning & are easy to apply. What saddens & disappoints me is that they'll lose their curl. It's so odd. The first time I used them, by the end of the day, I kept wondering why one of my lashes was looking wonky. Once I took them off at the end of the night, I noticed that the funny looking lash had... flattened out somehow as I was wearing them? Idk got it happened. It was as if I fell asleep in my makeup, ended up sleeping face-down on the pillow & the one side ended up flattened. But I did none of that. I gently cleaned them & did my best to try re-curling them by letting them dry while curled around a pen (had to do both this way so they'd be consistent). It somewhat worked. I got frustrated and threw them out. I do my best to reuse lashes at least 3x. I counted it as a loss. I bought another pair after that & took extra care to make sure there was no repeat. I was able to get 2 uses out of them, but the same thing happened. I tried using a heated lash curler on them to see if maybe that'd help hold the C-shape. No, it didn't. I chalked it up to these being 1x use lashes. I still think they're stunning, but won't but again unless they're on a very good sale.
