I used to do my brows with Etude House, but I wanted to look forward for waterproof ones so I purchased this! And... my thoughts? Totally a holy grail, I am never using other products than this! It comes with that jumbo one with a great brush to clean your job, you leave it one long night and in the morning you only wash your face, it stays like one week, depends how you clean your face and the products you use, so... In my case it lasts more like one week! It also comes with the Tattoo Kill Brow little one, I must say that I use it more than the other one, so perfect to paint and give my brows more personality!
