This is a set of 6 pastel-colored 0.4mm ballpoint pens. I bought them several years ago, but I haven't used them much, and I don't think I will in the future, so I'm selling them. I've confirmed that the ink still flows by testing them. Purchases are welcome anytime, but to prevent postal accidents during the New Year's holiday, I will refrain from shipping between the 30th and the 3rd.
