Manu Propria Pens - Roller Pen "Simplicity"

[Manupropria]

I spend some time to develop an as simple as possible roller pen design and came up with this solution. Ebonite barrel and end piece with "Negoro" urushi lacquer. By screwing the end piece in and out, the roller mine can be released and pulled back. Length: 13.50 mm, diameter 13.00 mm, weight 24 gr.

Bst regard,

Martin
