This will be one of, if not the tiniest liner brush you will ever get. The other that I know of is Goss 8. The bristles are very short so great for both gel & powder liner (push at lash lines); and even brow lining. It's not scratchy but firm. I didn't think I will like the pink color but in person, it's a very nice metallic deep magenta which looks modern & stylish. The passion series carry very uniquely designed brushes like this one & the eyeshadow one. Plus the short handles are great for travel!!

The RS4 is a nice brush and it is soft but firmer than expected, probably due to the squirrel blend with weasel. I do feel the koyudo C011 is softer and rounder & the goat hair blends pigment just a bit better. Like the other reviewer mentioned, the RS4 is more tapered to a point & can achieve better precision. I feel this works great for smoky eyes & intense colors in the crease.

As expected from Chikuhodo, Z8 is a luxurious brush versatile for applying blush & bronzer ( & even setting powder if needed). The squirrel hair is top quality & extremely soft. Yet, Z8 is still nicely dense without being too dense, perfect for sheer & soft-focused application. If for precise blush placement, I prefer Chikuhodo rc2 which is also all squirrel. This is my first brush from the z-series and i can see why it's so special. It's truly worth the splurge.

I choose this CMP527 brush as I have a lot of eyelid space and this size is great for blending and applying transition colors. I love it for mid-tone eyeshadows and the blend of squirrel/pony helps to deposit a perfect soft wash without being too sheer and amazingly, no harsh lines. This is soft but not as soft as pure squirrel or some goat brushes. Its tips are soft while the side is slightly scratchier. Comparing this with my other Japanese brushes, this brush is very similar, slight shorter, to Hakuhodo J5522. Haku is fuller, more tapered and pointier. After wash, the CMP527 is closer in shape to Wagne Goss 19 which is smaller. This is a very well-designed brush with great craftsmanship; but it's not the softest. I feel other makers like Koyudo & Chiku have excellent or even better brushes. However, this is a very unique brush due to the squirrel/ pony blend and it excels to serve specific purpose.

This brush is beautifully made and the quality is on par in comparison with the other Koyudo brushes I own. The goat hair is very soft (almost as soft as the Koyudo BP016 which is still more silky and delicate). It's also firm enough and quite dense (not as dense as Fu-pa 14). It performs remarkably well with pressed and loose powder to give an even, non-powdery luminous finish. I do love the slightly angled shape for multi-purpose use. It washes well and dries much quicker than BP016 and fu-pa. It's definitely a good-value purchase.
