This set arranges frequently used 15°, 25°, 35°, 45°, and 55° ellipses in 2mm to 4mm increments, ideal for design sketches and renderings. It's currently the only ruler set on the market that can draw ellipses from a minimum of 3mm (45° and 55° only) to a maximum of 100mm. This is a useful item not only for design but also for comic creation. I used these when I was attending art school, but some are unused and in very clean condition. The original price was a high 24,000 yen. The ruler in the 11th image was sold separately, but I'll include it as a bonus. * My name is written on the case label. See images 1-2. * My name is written directly on the bonus ruler. See the 11th image. * This is a personal item. Please understand that it is a used item, and those who are overly concerned about condition should refrain from purchasing. Please refer to my profile.
