This unique document holder can provide the same level of protection as other heavyweight sheet protectors, but without the pre-punched binding edge. If the page will be stored loosely instead of in a binder, this storage option has a much cleaner overall appearance. Use to post signs and protect frequently used materials. Top-loading polypropylene sheet protectors are made of extra durable heavyweight material. Acid-free poly material eliminates photocopy transfer. For 8 1/2" x 11" document storage.
