Well, I kept trying and trying to push the skinny end of the cartridge down onto the spike (which is sheathed in a plastic tube) and couldn’t so I turned it around to where the metal ball was hitting the spike and popped it right on. It made a bit of a mess on the little grey grill like thing, but didn’t leak and writes great!
I’m thinking cartriges for Matthew, for the time being...we’ll do the converter thing eventually.
Well...so there ya go. I’ve not used that type before - glad you got it figured out!
Does it also take some standard type cartridges, or just the Platinum ones?
