Brand: Colleen P.Co., LTD.
Made in: Japan
Rare, round, soft 4B. Front and reverse of same pencil. Not sure what it says on the reverse.
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.
