I've got a Faber Castell Ambition inked-up with Diamine Eclipse. Unfortunately it drys out after a couple of days of not being used. I'm not sure if this is a function of the pen's nib (it has no breather hole), the ink, the cap, or the storage. It is stored with many other Waterman and Kaweco pens in a dry box - none of which exhibit this problem.
Can anyone provide any insight into this problem? Having to dip the pen and invariably getting ink on my fingers each time I use it , is frustrating and discouraging its use. Will a change of ink make a difference?
