A brush made with Zaku to paint the wrinkles of a cloth. Since the long side is hard to use as a brush tip the handmade material of the short-shaped, soft rectangular shape, the boundary between the light and the shadow is made to stand out and the shadow color can be added by little at a time. It might be close to a flat brush as a sense.

It is such a feeling actually used. A hard nature is used for the part where the shadow is clear, and it uses a soft character in the part which wants to express the swelling.
