Brand: Colleen P.Co., LTD.
Made in: Japan
Three sides of the same pencils. The third side contains kanji.....or Japanese writing. Most likely an ad.
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.
