For sale: Parker oil-based ballpoint pen refills, standard type, black, M. Two refills together. Genuine product, unused. The logos and marks printed on the surface of the pen refills are smudged and not clear, but there is no problem with the writing quality. All refills are tested for writing before shipping. They are not in a hang-sell type package, but in a mini vinyl bag. We primarily ship from the post office, so we cannot ship on Saturdays, Sundays, and holidays. Thank you for your understanding.
