I'm just wondering how much paper do they hold. I know how big they are, but what I'm talking about is how sturdy are they? I've purchased the type from Office Depot only to have them bend under the weight of a lot of paper.
Can I put a Slab in each one of the trays and still have them hold up?
Here's a link just in case you've never heard of them:
