The thing is so narrow at the top that it is very hard to clean and I can't lubricate it (it's very stiff) because it's such a narrow opening.
I did do a search but saw no topics that seemed to speak to this and couldn't read every post in the forum to look for a possible reference to this issue. Do folks just put up with this or do you end up going to cartridges?
Are Cross cartridges international standard or proprietary? I already fill carts for my Sailor Minis so filling for my Cross wouldn't bother me at all.
