I was reading Alberto's article 'Starting a Bulb Collection II' yesterday
and noticed the statement that 'permanent' markers are not so. Friends of
mine in this area have been using the PC printed labels that they attach to
heavy vinyl and have seen these last at least five years. These labels  do
have the advantage that generating them on a PC ensures that labels and
inventory will be maintained consistently (all plant-related data). 

So, the question I have is: While nothing lasts forever, how long do these
'permanent' markers actually last?  I must be clear - I am not talking about
imprinted vinyl tabs, but the imprinted tapes that one attaches to a label
stick. I could not see any changes in what my friends (who have a large
bromeliad coleection) showed me after 5 years. From this I suspect the thick
vinyl will wear away first. Any comments?
