Just purchased a slew of these d-ring and round ring binders and they looked great and seem to function very well. The natural craft brown color is a nice look and is easy to add printed labels to or do your own designs or graphics on. The rings are sturdy, they may not be the best binders for constant or hard use, but for light use or storage they should be good. Eco friendly was not even my first concern, but its a nice added perk, they are much cheaper than most cheap plastic binders that really don't last all that much longer and then just add to the waste pile of plastic crap. If you wanted to use them for school, you might want to spray coat them with shellac or waterproof them, but for inside use they are fine. You can paint or draw right on the covers.
