The second flagship model from Jinni is the Hake-style brush, crafted from natural gray squirrel hair. This wide, flat brush with a moderate amount of bristles strikes the perfect balance between precision and a sense of freedom and dynamism. Unlike many similar brushes on the market, it avoids the rigid, mechanical geometry often seen in other models.

The resilient bristles provide a unique roughness, enabling a "dry brush" effect that is ideal for expressive strokes and textural accents.

Additionally, Jinni’s gray squirrel wash brush, featuring ultra-thin, highly absorbent soft hair and a solid wood handle, is perfect for professional watercolor artists. Renowned for its versatility and natural expressiveness, this brush excels in creating detailed base layers and fine washes, making it a favorite among watercolorists, particularly in Asia.
