A celluloid fountain pen is made. [Celluloid] Celluloid was a material that was used not only for pens but also for industrial products until the invention of plastic due to its beautiful coloring. General celluloid pens are made by cutting (hollowing out) a 17 cm square piece using a lathe, etc. But Platinum uses a material that is made by slicing the laminated celluloid material into a plate shape. Each piece is rolled up into a pipe shape and molded into the shape of a pen. Due to the nature of celluloid as a material, each process, including drying, takes a total of six months to complete. By continuing to use this unique method of winding, in the case of goldfish-like patterns, we can obtain a uniform and beautiful surface without the cuts that occur in the cutting method. In addition, the crown and tip of the shaft are rounded (curved) to ensure that each and every part of the pen is covered with celluloid, making this a high-quality fountain pen.
