KOKUYO TRAZER with Case It has some stains from use. Please check the photos. There are no malfunctions. This is a lucky item for passing the First-Class Architect exam. I used it for school. It's recommended to separate one for home and one for school, which reduces the burden of commuting. An A3-size file will be included as a bonus. I think it will be necessary for organizing materials. It can also be sold as a set with other materials.
