Review (5/5): like real hair growth
I bought this tatbrow pen for my daughter to try. She has always complained that the one she uses rubs off when sleeping and doesn't look as natural as she'd like. We got this and the lines it makes are so fine and natural looking it looks almost like real hair growth. Also, she left it on to sleep in, and even with her being one who sleeps on her belly with her face almost in the pillow, the next morning her brows still looked perfect.Strongly recommend.
