I have some problems with the ink flow on 3 Scrikss fountain pens they write very very wet for about 3 pages and after that they stop writing and you have to prime the feed in order to write again with those pens . I was thinking that must be a problem with the feed so in order to check that i am trying to remove the nib and feed without any success ! I mention that the pens are new and they have this problem from the beginning ! Anyone has any idea how i can remove the nib and feed on Scrikss fountain pens ?
