Review on 📁 5-Tier Desktop File Paper Organizer - White Office Desk Holder for Mail, Letters, and A4 Papers. Ideal for Home, Office, School, Classroom - Storage Rack for Documents, Notebooks. by Joe Gosa

I bought this 8.5 x 11 cardboard organizer. It's basically a solid foam core which is a little disappointing but seems to be holding up well. Thanks to some other reviews, I was prepared for tabs not fitting in their slots - and they didn't. But since it was a foam core, instead of trying to push it down and risking damaging the cleats, all I had to do was take a pair of pliers and gently squeeze the top of the cleats. This slight compression was enough to guide the tips into the slots without resistance, after which the parts could be pushed together. Just make sure you only squeeze the top tabs so you don't make them too small for the slots, which will make the whole thing wobble. Aside from that one extra step, it was very easy to put together. 4 stars because I had to do that extra step when assembling and it doesn't look as solid as I expected.
