Hello pen lovers, I have just found this at my late grandfather's, along with a tarnished and damaged C/F: http://www.pixenli.com/images/mini/1393/1393104022078266000.jpgLarger pic http://www.pixenli.com/images/mini/1393/1393104035029458400.jpgLarger pic http://www.pixenli.com/images/mini/1393/1393104088073127800.jpgLarger pic It appears to be an ink bottle case. It's marked "Jif" in red on the cap of the case, and there is a spring in the bottom. I searched a little on Google and here, but haven't found much. What can you tell me about such a case ? I also found the two steel four-coloured ballpoint pens I thought Bic was the first manufacturer ever. Any informations about them? Thanks you!
