i hate these converters. love my zebra g nib, but i hate having to use the osprey converter. it just isn't good. i've broken 3 of them so far. don't ask me how. i own a lot of pens and have used a lot of converters. worst i've ever used. hands down. my fingers have never been so inky day after day after day...

I am very impressed with the quality. Having lots of fun with these amazing pens. Thank you. Keep up the great work

-5 stars : TERRIBLE!
Both converters I purchased were obviously old and dried out. The one that came installed cracked and broke clean off the threads when trying to unscrew it. The second one did the same thing after first use.
