The choice of professionals worldwide, the Copic marker offers outstanding performance in all areas of design and illustration. Two versatile tips produce a range of strokes from fine lines to wide color fills. The roll-proof flat barrel is filled with alcohol based ink for a long life.
Basically, these pens are the best and worst thing that happened to my purse. I pretty much have every single colour...they don't dry out, they are felt tip, come in bold colours, and satisfy my desire to take notes in garish hues.
