Hello everybody in the land of knowledge:
   I have a question that really needs an answer, what type of marking pens 
are in use in various labs for labeling cassettes.
  In my lab pens by Secureline are in use, but have a very short life span. 
Even with careful covering, they dry out very fast. Any suggestions.?? This 
situation is the source of much frustration.
   Is there something better out there at a reasonable cost.??
   Your help would be very much appreciated in advance.
