ZEBRA ZEBRA Industry-Academia Collaboration Project New Spiral Two-Tone (Mechanical Pencil 0.5) Two-Tone Pink (& Gray) Brand New, Unused, Unopened This is an industry-academia collaboration series launched with the production of Professor Noda of Waseda University. It 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. It has been stored in a dark place, so 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.
