On the first day I was thrilled, but when I tried to sleep with them on the first night, I realized the lashes were far too stiff and were severely irritating my eyes. On the second day, it got progressively worse, and my eyes became increasingly red. Unfortunately, I slept with them on a second time, and the next day my eyes were red and very swollen. Removing the lashes was a real relief. What a waste of money.
