This "Hon Toshi Brush" in Japanese means the bristles are hidden in the wooden plates all the way to the end, just like a pencil core.
After the bristles are worn out, you cut off the tip with a knife and new bristles will appear!
You can also adjust the length of the brush however you like.
One brush can be the same value as 8--12 brushes!
What is special about this brush is materials are never-been-dyed human hair only. Why human hair?
A. Soft and delicate B. It has to be 18cm (7 inch) or longer for this purpose
The only alternative to human hair is horse's tail hair which is unsuitable because it leaves brush marks.
Urushi brush was developed in the Edo era (Year 1603 onwards) and is still loved by modern painters.
