Special Dense Ink 500ml (Boku-Undo)

The ink color is a brownish-purple, absorbing black. It is characterized by its strong absorbing black color when used as thick ink.
Made using slightly larger particles of brownish-purple mineral pine soot burned over an open flame, it is adjusted for viewing from a distance.
It maintains stable fluidity with minimal change in viscosity at low temperatures. It also works well as a mount in its original form.

Note: Cannot be mixed with products made from glue, such as solid ink.
