Since I'm in a "best of the best" mood, let's have a look at an excellent eye shadow brush from the elegant Hakuhodo Kokutan series. I've reviewed several Kokutan brushes in the past and I know I'm not the only one who can't resist these beauties with their ebony wood handles that feel warm to the touch. One buys them as a gift to herself and to her makeup, they're just that special.
Hakuhodo Kokutan Eye Shadow Brush WM has a short handle, but at 15mm(length)x 4mm (thickness) x 10mm (base) you can see it's similar in proportions to many medium-size brushes. The weasel hair is bundled quite firmly, allowing for some serious color packing (it picks up more product than the feather-soft S100 brushes). The Kokutan WM E0186 is quite precise and thin enough for crease work and other tasks using its curved edge. Several times when in a hurry I used nothing but this one and a fluffy blending brush for a full eye makeup, as it's so reliable, flexible and easy to use. It's that minuscule different of little extra length and less width/thickness that gives this Hakuhodo brush its advantage.
Bottom Line: worth every cent.
Hakuhodo Kokutan Eye Shadow Brush WM E0186 ($54) is available from hakuhodousa.com. They ship worldwide.
