ZEBRA Zebra Industry-Academia Collaboration Project New Spiral (Mechanical Pencil 0.5) Clear Color Series Clear Light Green Brand New, Unused, Unopened This is an industry-academia collaboration series launched with the production of Professor Noda of Waseda University. This is a mechanical pencil from the popular New Spiral series. Please refrain from purchasing if you are nervous about storage conditions. It has been stored in a dark place, so in my subjective opinion, the packaging is in good condition and is a beautiful item. It is expected to increase in value in the future. Please take this opportunity. Other discontinued/rare pens can be found here: #ZDiscontinuedPens
