505 001 PS2 mechanical pencil 2mm yellow

Primus range of products started in 1977. especially produced for students.
Triangles and other geometry sets in high quality yellow tinted plastic.
Range also included Primus technical pens in four nib sizes with bodies in different colors.

Also a unique PS2 2mm mechanical pencil came in this range in 1978.
Available in 3 colors to represent different fill types
yellow HB
orange H
green H2

This clutch pencil with simple mechanism is very handy features body made from quality thick matte plastic.
The cap included a sharpener.
The pencil was available in different variations and colors (burgundy, white and black) up until 1990.

It came in 10 and 25 pieces boxes, as well as individual.
This particular box is quite rarely found today and included 10 yellow pieces.

Strangely it had no HB mark, which is curious, so I am assuming this may be first primus generation, before rotring decided to make three colors each with mine hardness type-on.
What is more curious I have seen earlier versions of PS2, lighter yellow and with different body, aparently 1975. which would put it predate of Primus range.
