This 15 pack of size A4 file folders are perfect for organizing my genealogy documents. They come in five colors (3 each) and fit 8 1/2 by 11 sheets of paper. A small pocket holds a label card with ample room to identify the contents, and a snap closure keeps everything securely inside. With these file folders, I can separate my documents by family clearly showing on the included label which family is contained in a specific folder. This makes it much easier to just grab and go when I head out to do research. Also, the snap closure ensures that my documents won’t be scattered if I should happen to drop my folder. A real genealogist’s dream!
