501 810 1 Gamma mechanical pencil metal
Year: 1999

I thought all mysteries of Gamma series are found with 4 color plastic versions and a metal version of ballpoint.
But then I happen to find another...this metal Gamma mechanical pencil 0.5mm.
No much info about it is available.

Wondering are there more mysteries there to find.


A push button ballpoint manufactured in tough plastic with giant blue refill.
The ergonomic shape and non-slip grip area make Gamma a rock-steady writer.
Mechanism is bit different that standard fine leads...and the pen doesn't have space for eraser.
