I have a customer that wants avery thin postable rollerball. The thinnist I have founf is the Screw Cap Rollerball Kit at Woodcraft. But they want thinner, no black plastic and titanium/platinim/Rhodium plating.
Does anyone have any suggestions?
Ever since Smitty37's pen swap, I've been looking into the Streamlined American from Berea, as well as the Flat Top. From what you describe, I haven't been able to find anything that meets your requirements.
The New Series comes close, but only comes in Upgrade Gold, and Chrome.
If you don't like the center band of that, you can always use parts from the Flat Tops to make it all metal in a more plain look.
