Z-9 Powder Brush ($226.00) is large, rounded, slightly flat brush with medium-full density. The brush is made out of gray squirrel hair, and the brush head is 55mm in length, 40mm in width, and 26mm in thickness. It had a total length of 6.5 inches or 16 centimeters with an open ferrule. When it came to apply setting powder, I preferred this slightly more than the Z-1, because of the flatter shape, which enabled me to press the setting powder against the skin, rather than with more sweeping motion. For setting powders, I prefer pressing and patting, and for finishing powders, I like the more feathery, sweeping motions. The end result is very similar, though, regardless of the brush used. The Z-9 can be used in sweeping, patting, or pressing applications, and it feels like silk against the skin.
