Information tool. Created with the motto: "Anyone can become a fun and intellectual producer." This is the ultimate tool for information gathering and learning, making anyone want to study. It's an incredibly user-friendly size. It's based on the Kyogata card system developed by Tadao Umesao, the information producer concept of Chizuko Ueno, and the note organization methods of Yasuo Noguchi, with many usage examples. This method of information gathering, organization, and analysis is currently being re-evaluated and developed overseas. In Germany, there are books (zettelkasten) and apps like Notion, Obsidian, and Zettlr that have evolved from the card usage concept. Handwriting is key to generating ideas. (For reference: Creating an index or table of contents makes it even more enjoyable.) 【Specifications】 Size: 15 x 23 x 4 cm Hardware: Large-diameter (33mm inner diameter) Color: Red cowhide, with a thick leather lining made of two layers of leather.
