These are perfect for all sorts of projects not the least of which is my Recipes binders. For recipes I use regularly I print them and then use the sheet protectors to put them in my binder without needing to punch holes in the recipe itself. That means I never have a hole in the middle of some word that got too close to the border! AND I can quickly lift them out of the binder and clip them to the stove hood when I'm using them and they stay clean and ready to go back in the binder when I'm done. No fuss no muss!
I use these protectors constantly to store work for my job as a magazine editor. Then after publication they protect the issues and makes it easy to keep in a binder contributing to my "portfolio." The price fit my budget nicely too.
