Inquiry (采购产品): regular photograph sleeves Please tell me the difference and which you recommend between polyethlene for polypropylene photo sleeves for long term storage. Which mil thickness should I use? These photos are family heirlooms and I want to take the best care of them with a product I can afford. I have several hundred photos of varying sizes. Thank you for your assistance. **** Hidden Message ***** Nancy Green TX 75052 USA Company: private use only Title: homemaker E-mail: nogreen341@sbcglobal.net **** Hidden Message ***** nogreen341@sbcglobal.net
