I don't use the Tim Holtz things for storage, just 8.5x11" storage sheets I made myself, slipped into page protectors. But I wanted to comment on the overhead projector sheets that someone asked about. I began using overhead projector sheets as my "cling" sheets about 5 yrs ago (they are attached with ATG adhesive to cardstock or chipboard backing). I have stored all of my stamps on the sheets including clear acrylic, clear photopolymer, and red rubber (my rubber stamps are mounted various ways ranging from no foam + 2-way adhesive, to mounted on EZMount or Stamper's Best cling foam). None of my stamps have had any issues at all after 5 years of storage. Because of testing this myself, I do not believe that overhead projector film is harmful for clear or red rubber stamp storage or my stamps would have had issues long ago.
