50 Pcs A4 Clear Document Folders with 60 Tabs, Waterproof Plastic Sleeves with 11-Holes for Binders, Organizing Papers, Files for School, Office, Business, Home Use

These are nice, sturdy plastic sleeves to protect your paper. I like using them for recipes, but you can use them for anything you would like. They have multiple holes to fit almost any binder. They are larger than your standard 8.5 X 11 paper, so they will be larger than your standard paper. They will also fit a standard binder, but may tend to extend a bit past the binder edges if it's exactly 8.5 x 11. You can use A4 paper and binder for a perfect fit.

Ok so they're definitely for A4 sized paper. I saw the dimensions and thought they could work for my standard size 8.5x11" cooking binder. These are bigger, so you'll need to actually have an A4 binder and use A4 paper to maximize its potential. Otherwise, these are medium-ish weight and the hole cutouts are really versatile for a lot of different binder configurations. Clear with some nice tabs.
