I use these sheet protectors for my extensive recipe collection. Once I print them off I put them in the insert protector then into a three ring binder. When making a particular recipe I remove it from the binder and it stay protected from spots and spills.
I did not want insert sheets but wanted an clear portfolio that contained only the insert sheets. Staples did not have it. So I bought this. I'll put it into a folder.
These were mostly fine but one of them had not been manufactured correctly and was unusable due to some excess plastic. Didn’t feel worth it to return (and waste) all 25 for one bad one but would have been nice to get what I paid for in useable condition.
