Innisfree Gel Eyeliner Brush

I use it as an eyeliner, but I also use it to apply a thin layer of shading along my eye line. I usually use it when adding eyeshadow shading. It seems perfect as an eyeshadow brush. The bristles aren't too thick and have a blunt style, so it applies very naturally and smoothly. I find it useful for blending out harsh lines. I like that it allows for precise application.
