the brow pens aren t waterproof [SEP] i like that the pen is for your brows and the other end is an eye liner you brow pens for under and that s a plus the color is pretty true to what you see in the pictures light brown there is a learning curve when putting it on but it didn t take to long to figure it out the pen doesn t make little hair line strokes continuously i purchased the pen because the description said it was water proof but after having it on for about hours it started coming off this was with light perspiration walking from the car and into the store in degree weather when i received the brow pens one did not work i contacted customer service they responded back to me right away and sent a replacement to me immediately so customer service is awesome
