What is the length of refill?

Length - 2.6" (66.0mm) Regards, Jim

Which Schmidt pens do these fit please?

I personally bought those refills for a Swarovski pen .

Will these refill cartridges fit rotring 600 3 in 1 pen?

I have a rotring tikky 3in1 and I wasn’t sure, so I looked up your 3in1 online and saw that yes, the 600 takes D1 refills

does this fit a keySmart nano pen?

It’s a standard size D1 refill
