I just got these pens... literally out of the box and 3/4 of them aren't completely filled with ink. One of the blue ones (see photo) has so little ink that it looks completely empty. This was not a cheap set compared to others available, but the colors looked nice and I thought I'd give them a try. At almost $30, I should have just stuck to the cheaper sets. At least it wouldn't have cost me as much to replace them when they ran out of ink.
