Original product purchased around 2010 at Bundo, Ochanomizu, Tokyo. The box size is 24.8 cm x 18.5 cm x 7.7 cm, about the size of a B5 notebook, so it's smaller than what's usually sold. It fits in a small bag and is convenient to carry around. Although it's unused, there is some rust on the metal parts and some scratches on the box due to aging, but I think it's in good condition. #wadacchi
