For Sale: Parker Oil-Based Ballpoint Pen Refills - Standard Type - Black M Genuine, Unused, Set of 2. There is some smudging on the printing of the logo/mark on the surface of the pen refill, but this does not affect writing. All refills are tested for writing quality before shipping. They are not in a hang-sell type package, but in a mini-plastic bag. We primarily ship from the post office, so we are unable to ship on Saturdays, Sundays, and holidays. Thank you for your understanding.
