Hardly visible CV/GATE/MIDI IN/OUT back engraving?

If like me, you have to install and uninstall your setup often and be able to quickly plug into the right inputs day and night?

A simple POSCA PC.5M pen with pigments allows you to pigment the background of the engraving and wipe off the excess on the surface.

It’s clearly more readable and avoids having to put tape or ugly labels :wink:
