Unused Parker oil-based ballpoint pen refills, standard type, black, M. Two refills together. Genuine product. The printing of the logo/mark on the surface of the ballpoint pen refill is smudged and not clear, but there is no problem with the ink inside. All items are checked for writing quality before shipping. We primarily ship from the post office, so we cannot ship on Saturdays, Sundays, and holidays. Thank you for your understanding.
