I’m finding very little information on the Rivette, but it sports the reliable basic rOtring nib.  It is plastic and lightweight but a decent diameter.

I have two of these available, both new and unused, both with fine nibs.  One is in an unopened box, the other has no box.  The latter includes an international cartridge and a dummy cartridge in the barrel, which I’d guess the former does too.  Nice feature that you can have a backup cartridge on hand, or I suppose you could fit a long cartridge.

Two available.

Asking $40 (new in box) or $35 (new, no box) plus shipping
