Chikuhodo GSN-09 Eyeshadow Brush is a brush that retails for $25.00.
Chikuhodo GSN-09 Eyeshadow Brush ($25.00) is a small-medium, dome-shaped eyeshadow brush made out of gray squirrel hair. The brush head had a length of 12mm, width of 6.5mm, and thickness of 2.5mm. It had a total length of 182mm with a pinched, metal ferrule. Of all the GSN brushes I've tried, this is easily my favorite, and I could see getting multiples of it, because it's a really versatile brush for eyeshadow application. It's narrower than my go-to MAC 239, but it is softer with a more domed edge. The narrower width allows it to apply color more precisely, which is helpful if you're using more than two or three colors on the lid. It packs on, sweeps, and diffuses eyeshadow beautifully. The edge also fits into the crease area well and can apply color there, too, if you don't have a go-to crease brush (or sometimes get lazy, in my case). It's incredibly soft and silky against the skin, but it still picks up plenty of product, so you don't sacrifice color payoff in your application.
