dissolving it with alcohol-typed solvents.

A pen of COSBO effers sharp and clear letterings on a whiteboard. Also, you can easily clean up the witheboard, whether a pen of COSBO is used just now or long time ago.

A simple dispersion process of COSBO saves costs in production and solvent usage.
In addition, it helps you keep workplaces cleaned, because COSBO doesn't fly in the air while poweder-typed pigments does.
