Can someone please tell me what's the pen used here in the below URL called? It looks like a Gel pen, but the text written with it is so sharp:
Does not look like a Pilot G1 to me, not the point anyways.
The pen in the picture can be a Technical pen
Hard to say from just the pics but almost certainly it's a gel rollerball pen with a very fine nib, probably ~0.5mm. Looks very much like a Pilot G1 to me.
