Montblanc Clamping Rings X4 + X2

CLAMPING RING FOR MONTBLANC 'X'4 SERIES PENS (14, 24, 34). X2 RING ALSO FITS MB 31.  This is that tiny, thin chrome ring on the connector between the front section and the transparent ring of the series of pens whose two digit model #s end in '4' that always gets lost without your knowing it. It rolls away and you didn't even hear it drop. And you're not going to find it no matter how much you crawl around on the floor looking for it. The X4 dimensions are: outer diameter is 11.36mm, inner diameter is 9.6mm and thickness is 0.37mm.

We also have these for the No. 22 + the '2' series. Request the MB 22 Section Ring for that size. ALSO FITS MB 31. Its dimensions are: outer diameter is 10.7mm, inner diameter is 9.0mm, and thickness is 0.38mm.
