Copic Sketch Marker Pen Nib Refill - Medium Round Nib - Pack of 5

Just received my pack of round nibs and already switched one with the Super brush nib on a black 100 Sketch marker. I would have liked to have a Super brush nib on one end and the medium round on the other, but the medium broad brush nib end will not accept either one. Freshly installed, the medium round marker nib performs nicely affording greater control and uniformity of line than the Super brush nib. Suitable for cartooning and drawing caricatures like a good alternative to the harder-to-find Dixon Markette marker pen.
