Thanks for the warning. My markers are really good, however, if I make a
mistake, the writing stays on very nicely and the current lot I'm using
won't come off even in ethylene glycolmono ethyl ether ... This was the
only substance I found that would remove the writing and it came in handy
if I goofed up my labels. Now I have to throw the whole slide away. There
seems to be a lot of variability in the ink with these. Some lots the ink
comes off, others are just fine. weird.
