I found this while cleaning. I am selling it to declutter. ● Hayakawa-style mechanical pencil, a reproduction of the 1915 (Taisho 4) invention The name of this pencil is the origin of today's Sharp Corporation. This is a rare item distributed to related parties to commemorate the 77th anniversary of its founding. ● Refill leads: Contents included in the case ● Lead thickness: 0.5 mm ● Length: 13.4 cm It has only been used for test writing on the paper inside and has not been used otherwise. It is new and unused, and the case is also clean (see photos). Please refrain from purchasing if you are nervous about the condition.
