Item: Faber Castell TK-Matic Automatic Feed 0,5MM Mechanical Pencil

Model & year: 9725 first version. There are at least 3 versions of tk matic and tk matic L. The main difference is inside cartridge, last version has 4 places made by plastic in the cartridge. The first version cartridge is made full metal

Condition: new with rare box

Description: first version has red eraser, later version has green eraser. This pencil cannot be disassembled because this is still the original status from factory and never been used. But if you disassemble the cone part, you can find all metal.

And this glue only happened in the first version!

This box is also very rare, unique and I may be the only seller who has this box, it is said this is the earliest box as well. But after that, Faber castell saved the cost for it.
