MAC 219 has become one of my favorite brushes! This clever rounded brush with a pointed tip is great for blending liner and shadow under your eyes to make them appear bigger. For someone with smaller almond-shaped eyes this is a wonderful brush!
The bristles are a great length, not so long that you can't blend and not so short that it's too stiff. I use this brush on the upper lid blending in eyeliner (powder). All my MAC brushes are really good....no matter which one I use/buy, they always work out great.
