The best pens I have used are also the Secureline Marker II / Superfrost.  
Sometimes you have to scribble with them a little while to get them going 
unless they are very fresh.  They work very well, I just wish they cost less 
so we could afford to use them routinely here.  I used them for slides and 
cassettes for years at my previous job with great success.

We use Secureline Marker II / Superfrost for our cassettes and slides. Only
problem is they dry out quickly if you don't keep the cap on.
