A special variant of the famous Mitsubishi Uni pencil.
The Jumbo-uni is 25cm long and 1cm in diameter!
The appearance and markings are generally the same as the regular Uni. Some text is different:
It really is Jumbo:
Uni pencils mention the company establishment in 1887. “85th anniversary” suggests 1887 + 85 = 1972. Is this pencil really 38 years old? Well done, Mitsubishi Pencil Co.
