This product was so perfect, I had to write my very first review! It came with both 5x7 and 8 1/2 x 11 plastic sleeves. When I purchased, I read many of the reviews and one of the concerns was buying the replacement 8 1/2 x 11 sleeves from the manufacturer because they didn't quite fit. The sleeves that come with initial purchase fit perfect. I bought extra 8 1/2 x 11 plastic sleeves for a standard 8 1/2x11 notebook from Staples. Works great!
I recommend this product for anyone who loves to cook and collects recipes!
