Demonstrator (Yellow) – Medium

The OPUS 88 Koloro Demonstrator is a dedicated eyedropper pen with an acrylic body. The semi-transparent body also allows for ink to be seen swishing.

This pen utilises a #6 branded German nib for an amazing writing experience, and comes with an eyedropper tool included.

Note: The demonstrator is slight larger than the coloured series. The cap also cannot be posted.
