aper is fragile and susceptible to damage and deterioration, yet it holds some of our most treasured memories: childhood keepsakes, awards, newspaper clippings, graduation programs, military records, wedding invitations, career milestones, photos, artwork and much more. You are the guardian of your family history. Protect it with these archival-quality envelopes with nonadhesive flaps from Gaylord Archival. A practical alternative to vertical file folders, they store easily in document or print boxes. 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. Made in the USA. (Please note: Parchment and other materials made of animal protein should not be stored in buffered envelopes.)
