This pen looks very interesting--totally new, affordable and a piston filler?? I can't believe it. I may buy one for my sister as a birthday present, but personally not something I would carry around with me. Do you think it is a real piston filler, or a trapped converter? Based on the knob shape, could it be like Stipula's Etruria models?
