Ok, so the files are sturdy, an almost glossy green, not fuzzy cardstock or anything. But what is quite absurd, is the paper tabs that came in the SAME SEALED BAG as the plastic holders for them DID NOT FIT said holders. They're not wide enough and too deep. I had to trim with a scissor to insert them.
And no, I know exactly how they fold so it's not user error, and since they all come in the same bag it's not a product that someone bought, messed with, and returned mismatched to the store.
So if you don't mind a quick snip buy these. They're otherwise decent quality. Or you can chuckle at the absurdity.
Two of these file boxes fit side by side nicely in a single cubby in [brand] shelving unit.
These are built much better than [brand] boxes -- which, sadly, I bought before finding these from Target.
