I just finished a batch of 50 pens for a customer. I found 5 or so that sounded like something was loose inside when trying to write with the pen. I swapped out the transmission, spring & cartridge, one at a time to see if the noise would go away but it didn't. Could there be something in the nib end that is loose? Fortunately, I had some extras hanging around just in case. Has anyone else come accross this issue?
