This is a bulk sale of various writing instruments, including ballpoint pens, mechanical pencils, markers, and colored pens. There are various items, from new to used. Only the light blue ink of the multi-color pen does not work. I haven't checked the new items in the bag, but I have confirmed that the others are usable. Some items have been stored for a long time. Please understand that this is a personal inspection, so I appreciate your understanding.
