We used the refillable style pens which can be messy, but it did allow 
the cleaning of the nib in the ultrasonic cleaner. This was almost 
always needed before use. At one point our department assigned someone 
to clean the damn things every morning in hopes of them being useful all 
day. Occasionally that would hold true. :(
