Purchased last year. Used a few times, and some pen tips have black marks. Overall, there's a sense of use, but there's still ink, and most of them can draw cleanly. However, three pens (YR31, Y11, Y02) have a slight mix of black ink. The black ink should disappear as you draw, but please be aware of this. These are used items, so please refrain from purchasing if you are overly concerned about condition.
