Here's a KS8300 in red (2 views).  This is one of the less common colors.

I have several of these in Green,  Black, Red, Yellow, and light Blue.
None have the ball end, and are not marked KS8300.

These are the Mark/Sense pencils designed for marking computer cards for machine reading.... Sort of fill in between the lines so it can be read.
