Brand: Colleen P.Co., LTD.
Made in: Japan
"Jugo sen, Made in Nippon, HAP, Colleen Pencil (logo mark) HB."
"Jugo sen" means "Fifteen cents", the price!
The cent for yen was only used untill 1953.
Most likely pre-war or mid-war era.
Founded in 1916, Colleen liquidated its assets in 1997. At one time it was considered one of the big three Japanese pencil manufacturers. Interesting to note that in 1982 Colleen flipped its triangular-shaped logo from right to left, and also changed its logotype to a round gothic font.
