(Old) JIS mark

In Japan, the Japanese Industrial Standard (JIS) mark has been introduced for pencils since the 1950s,

but as the pencil industry technology stabilizes,

the JIS mark is no longer displayed on pencils from the late 1990s.

< Compare the logo with the current colleen pencil (bottom) >

In February 1982,

the direction of Colin's logo triangle was changed from right to left.

The logo of the Colleen No.718 pencil is on the right,

so it can be estimated as a pencil before 1982.
