COPIC ink refill for COPIC Ciao, Sketch, Wide and Original markers. This 12ml alcohol-based marker ink comes in a pen-shaped, transparent bottle with an eye-dropper spout for easy refilling. Colour matches COPIC markers and can be intermixed to create your own unique colours. Copic nib tweezers are available and make nib-pulling easier. This is the replacement for the Various ink refills. The bottle is marked with capacity gradients.
