Copic Marker-Tweezers. Use the tweezers to remove a nib and refill a Copic marker with ink. They prevent damage from occurring to the nib and keep the ink from getting on your fingers. Gently grab the nib and pull. Once you re-insert the nib it may take a minute for ink to flow. Ideal for removing broken brush nibs. To prevent wear on the brush nibs, always refill from the chisel end and avoid pulling out the brush unless damaged. They work on Copic, Sketch, Ciao, and Wide markers.
