It is grey squirrel mixed with synthetic.
The hair shape is similar to that of B004.
The last picture shows Kokutan eyeshadows relative to B004.
From the top,
Kokutan eyeshadow SG (goat/synthetic)
Kokutan SC (tamage)
Kokutan eyeshadow GS (grey squirrel/synthetic) > new one
Kokutan eyeshadow ML (grey squirrel/synthetic)
Kokutan eyeshadow MLL (grey squirrel)
Kokutan eyeshadow GS (grey squirrel/synthetic) is a new one.
I thought it was 100% grey squirrel but it is mixed with synthetic, I was informed by Hakuhodo today.ko
I know most of you like 100% natural hair.
Hakuhodo told me that this shape is difficult to make with 100% squirrel because it is too soft.
