Miffy ballpoint pen set of 4. [Ink: Black] Stored at home, unused, but there is some staining on the knock parts due to aging (photo 11). I have confirmed that all 4 pens can be used for writing tests. The ink levels are about the same for all 4 pens (photo 10). Yu-packet post, anonymous shipping. * Please note that there may be delays in delivery during the New Year holidays. Thank you for looking.
