This is a rosewood piece with a strong reddish hue. It is slightly softer than ebony. The sound is gentle, I believe. It has a glass coat finish. Our workshop is the only one that applies a glass coat to the chin rest. The glass coat is an eco-friendly paint that does not use any solvents such as thinner. Size: Length 12.5 cm, Width 6.5 cm, Height 2.5 cm, Weight 42 grams. The texture is very smooth, and the feel is completely different. This is my personal impression. Handmade by Yuji Matsuoka, a regular member of the Kogei Association. Comes with a decorative paper box and a brief history.
