ZEBRA Zebra Industry-Academia Collaboration Project New Spiral (Mechanical Pencil 0.5) Pink New, Unused, Unopened This is an industry-academia collaboration series launched with the production of Professor Noda of Waseda University. It's a mechanical pencil from the popular New Spiral series. I think it's rarer than the ballpoint pen version. Please refrain from purchasing if you are sensitive to the condition, as it has been stored in a warehouse. It has been stored in the dark, and in my opinion, the packaging is in good condition and is a beautiful item. It is expected to increase in value in the future. Don't miss this opportunity.
