For sale: Parker oil-based ballpoint pen refills, standard type, black, M. Two refills together. Genuine product, unused. The logo, mark, and text printed on the surface of the ballpoint pen refills are smudged. However, they are unused, and there are no problems with actual writing. We will check the writing quality before shipping. They are not in the usual hang-sell type packaging, 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.
