I give these to students to keep important formula sheets and reference papers. It keeps the papers protected and helps students find their reference sheets. Threes sheets protectors set them apart from all their other notes and homework papers. Also good for recipes from magazines or the Web. Recently I used these for lost cat flyers that i posted on signposts at shelters and vets and gave out to people all over the area. Durable weatherproof. Also good to put lettering and pictures inside for on larger posters and signs. These have 3 holes to fit binders and fit full 8.5x11 papers inside. You don't hole punch the papers you put inside. These are clear easy to read through.
In re-doing my cookbooks I copied the recipes I wanted to save and placed into these sheet protectors. The nice thing is as I get new and more recipes I will be able to pull ones out and switch and make more space. They also keep the papers clean while I am doing recipes. There have been many times that I got flour oil etc. on the pages of my cookbooks. These page protectors keep those recipes safe and I can just wipe them off. They have greatly helped with my project to consolidate my cookbooks. I am now working on two cookbooks and may have to go to a third. But this is better than having 27 cookbooks in your cupboards.
We make our own music books for each holiday at our church. This is the best way to keep our pages from becoming worn and torn. The next time I get them I am planning on buying a case so I do not run out in the middle of a project. Do not waste your money on the name brands.
