I had been trying to add a flex nib and a stub nib Snorkel to my collection, and I managed to kill two birds with one stone.
I was not aware that these were even made (honestly it's just so impractical), and from what I can tell, they are pretty uncommon. If anyone else has more insight on that, please post below.
Please ignore the poor handwriting - I've never used a stub nor a flex nib before, so I'm definitely not doing it justice.
I saw a couple of posts about flexible stub Snorkels here while researching a bit, but would be interested in seeing any that other people may have.
