I held onto mine forever and just recently got rid of mine. I had never even opened them. I can check with my friend and see if she plans on using them. I just put a bunch of stuff in a box and sold her a ton of items. She may not even use them.
They didn't really work for me but considering I never opened them says alot right?
I check with her and she is wanting to keep them. You might be better off with using pagemaps and sketches anyway. Just my opinion. They are and were pretty dated.
