Unused, unopened. [Product Overview *Quoted from the HP*] With so many people working in front of computers for work, study, and hobbies, a horizontal desk notebook with an exquisite size that can be neatly placed in front of the computer has been created. Available in two sizes to match general 13 and 15-inch laptops, it can be used vertically or horizontally and can be installed in a space-saving manner. The 15-inch width, which is slim but allows for ample writing, has a separately sold dedicated notebook band for convenient portability. The body colors are three traditional Japanese colors: 'Pale Green', 'Gray', and 'Dark Gray', which are sophisticated while maintaining a chic color scheme. Both the cover and the inner paper use "bagasse paper" made from bagasse pulp, which is made from sugarcane residue. Bagasse is a byproduct of sugar production, and the surplus is treated as waste. Utilizing bagasse paper allows for the use of unused resources and contributes to waste recycling. In addition, using bagasse as a paper material not only reduces the amount of wood used, but also reduces the energy required for felling, collecting, gathering, and transporting wood, and there are estimates that it can reduce CO2 emissions, making it a material that can contribute to environmental conservation. The 3mm grid lines that beautifully decorate the notebook are in 'Byakuroku (Pale Green)', which is also the brand color of CDT, and are finished with a subtle presence that does not interfere with thinking. The usability is also excellent, with a design that incorporates triangles on the left and right edges of the front and back covers, allowing them to be used as bookmarks, numbering, and indexes. This is a book that lightly updates the conventional notebook and leads the way for the future.
