I should clairify that I have not used airtites in over 15 years, they may have changed the quality somewhat in the past 15 years. Mine used to scuff rreally fast leaving hairlines all over the face of them. The edges seemed to be quite brittle and cracked often. I may have to try some out again as I see so many that do like them. I would think they would be really good for keeping proof coin in.
