Thank you for viewing. Although stored by a private individual, it has been kept in a dark place. This is a set of 9 Zebra 0.5 ballpoint pens and 1 0.3 ballpoint pen. Used a few times, but there is almost no ink depletion or dirt. I have tested them out. If you purchase this item together with other items I am selling, I will offer a small discount. Also, I am open to some price negotiations. I will package them to prevent water damage and folding. Feel free to leave a comment!!
