This is an aluminium anodized high quality ballpoint pen. The movement is inspired in a sketch described by Leonardo Da Vinci during the 15th century in some manuscript.
The design is totally made by artisan in cnc machining one by one and there is no complex mechanisms inside.
The user only need to turn the side tube and the ink refill go up and down by a mechanic and simple movement.
Less is more and as a sentence of Leonardo Da Vinci says “the simplicity is the ultimate sophistication” in this design.
This pen won the European Design Award PLATINUM (the maximum award) in the office complements category.
