PEN

Presentation: Carton recycled, free for each pen
Mechanism: Fixed in the mass, threaded rod out of metal for each ball pen
Personalization: Process by engraving with the lazer (not of film expenses):  your logo, name of company, n° of such...
Perhaps engraved on the part of the pen... your proposals & projects are welcome.
The more you use your ball pen, the more wood patinate, the more it embellishes.
