For Sale: Parker Oil-Based Ballpoint Pen Refills, Standard Type, Black, M. Genuine, Unused, 2 Refills. The printing of the logo/mark on the surface of the ballpoint pen refills is smudged and not clear, but there is no problem with the ink inside. All refills are tested for writing before shipping. These 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.
