I bought this because I needed a brush for dark circles and concealer. I saw it on Haemae Collab's YouTube and decided to get it along with some other things. The size is about the size of my thumb, and I didnโt have to do any special shaping, the bristles donโt split, so I just used it as is. I mainly use it for dark circles, and when paired with the Canmake concealer palette, it makes dark circles disappear instantly. I also tried using it with Laura Mercier Camouflage and Erborian BB cream to cover skin troubles, and it worked well. Itโs easy to clean, reasonably priced, and versatile, so I highly recommend it.
