We're manufacturing new cartridges for customers.
We're finally checking the sound.
These photos are part of them.
Red one is painted URUSHI lacquer and inlay which points to the stylus. It's a special model.
White one is standard model. Not painted, just CORIAN itself.
The sound character is a little bit different between them. Because one is painted another is not painted. It will iaffect the vibration mode of the main body.
I hope you can find the difference.
