ZEBRA ZEBRA Industry-Academia Collaboration Project New Spiral Two-Tone (Mechanical Pencil 0.5) Two-Tone Orange (& Blue) Brand New, Unused, Unopened An industry-academia collaboration series launched with the production of Professor Noda of Waseda University. This is a popular New Spiral mechanical pencil. This is a rare two-tone series. It's quite valuable. Please refrain from purchasing if you are nervous about storage conditions, as it has been stored in a warehouse. In my opinion, the packaging is in good condition and beautiful because it has been stored in the dark. It is expected to increase in value in the future. Don't miss this opportunity.
