Paper is fragile and susceptible to damage and deterioration, yet it holds some of our most treasured memories. Take the time to protect your treasured holiday and vacation memories from damage caused by handling, dirt and light with this Gaylord Archival Postcard Preservation Box. Commercially available items sold as "acid-free" actually begin to degrade within just a few years, but products that are truly archival quality provide protection that lasts generations. Handcrafted in Syracuse, NY. Passed P.A.T.
