The practice pack was okay for learning how to put the gossamers on, but that's about it. I do however appreciate that you sent the B gossamers with the practice pack. Was hoping I would get at least a night and the next day wear out of them, but they didn't last through the night 😕 Not sure if it was the bond or my error, but went ahead and ordered the Control Kit with the C gossamers. I received it yesterday and put them on the minute I got home. They have lasted all night and so far all day at work today. Love this system and I'm so happy I found Lashify. ❤
