Question About Reusing Montblanc Shoe Bottle

[Foyle]

I have an old Montblanc ink bottle that I'd like to dispense some ink into. The problem is that the plastic (or is it paper) cap seal is missing. Do I need to replace that in oder to ensure the cap will seal properly? If so, what could I use?

My guess is it's useful, but not essential, at least for non-long-term storage. Of course, you could always take a cap liner out of another cap of similar size (if not identical size, larger and trim it down. I suspect there is more standardisation in cap size than you may expect, and a suitable replacement is probably not too hard to find.)

I've made one out of a styrofoam cup (when they were still legal in my area) for a Sheaffer's bottle but Ian's suggestion sounds better.

Those Montblancs are classy bottles.

There's a high probability that there is a replacement inside the cap of the ink you plan on putting into the MB shoe. Sheaffer, MB, Akkerman and some Parker bottles really were designed to make filling easy.

Blotting paper?

It´s a little bit late, but maybe it helps others.
You could use a flat rubber ring or cut out a piece of rubber and fit it in. It should seal the bottle perfectly.
