Currently I am using them to hold genealogy pages.. They are very protective for items that are handled frequently with some being old and fragile. I would recommend them to anyone.
I am making copies of MY cookbook for my son and daughters for Christmas. These make beautiful and cleanable protection for the pages. Spills won't ruin the page and they are inevitable. I will be ordering many more.My cookbook has 285 pages and I'm making 6 of them.
