I got several emails after showing you the makeup brushes I packed for my recent trip, and most of them were about this beauty, Hakuhodo S122 eye shadow brush. This is truly a rock star, even among other Hakuhodo S100 series items. The thick and full head (9.5mm, about one third of an inch) is made of uncut Canadian squirrel hair (according to Hakuhodo customer service no animals are harmed in the process. I dearly hope it's the case). The rush has great bounce without too much give, it's exquisitely soft but not floppy, so the shape allows for a lot of control.
You can easily tell that S122 is different from other contour brushes, including another Hakuhodo, the G515. The slant or angle is moderate (compare to the one from Sisley, for example), and the shape is very organic. The wonderful thing is how well the S122 multitasks (which is why I took it with me to Paris). It does a wash of color as well as contour and even detailed work- depending on the part of the brush you use. And have I mentioned how soft it is? I did, but it's worth repeating.
Bottom Line: precious.
