How do I refill Copic markers?

Firstly, make sure to match the exact same color of Copic Ink with the marker you plan to refill. Then remove the broad (angled) nib of the marker using tweezers. Insert the ink nozzle straight into the core of the marker and add an appropriate amount of ink. The amount of ink depends on how much ink is left in the marker, but we recommend that you add around 1ml (one mark of the bottle) each time. Click here to learn more.
