I’ve located another source for archival quality pages that can be used for collecting patches, BCW Supplies.
According tio their information, their Polypropylene Pages:
Heavy-Duty Polypropylene Material (115 micron)
Archival Safe (contains no PVC)
Highest clarity available
Material manufactured in USA
Highest weld strength attainable for this material
Straight bar seals
Designed for 3 ring binder (holes punched & cleared)
Foil stamped BCW logo
The pages are generally available in quantities of 25 and 100 in the sizes usable for patch collecting and some unusual sizes for other purposes. They have single pocket(neckerchiefs and jacket patches), 2 pocket (2-piece sets), 4 pocket (3″ rounds or other smaller odd-shapes) and 6 pocket pages (for CSP’s and flaps).
They also have other supplies such as 3 Ring D-clip binders and comic and magazine backing boards. I use the acid free backing boards and cut them to size to fit the various pocket sizes of the pages. this makes for a cleaner appearance and can double the number of patches that can be displayed on each page.
They can be found by clicking on the banner link below.
