These are fantastic organizational bins! They're made of a stiff canvas-like fabric, with separate fabric-covered cardboard pieces that you insert into the bottom to stabilize them. They're collapsible, so you can store them flat when not in use. And they have large silver grommets that serve as handles, so you can easily pull them out from a shelf, or carry them. They're a decent size, too.Best of all, they have matching lids! I love this feature because it means I can fill the bins with fabric, or notions, or whatever, then put the lid on, so you can't see the mess inside. It really helps your room look tidy. They were a bit pricey when I ordered them, but they're very high-quality, and you get two bins, not just one, so it's worth it. I got them for my sewing room, because my cutting table and ironing cabinet both have lots of cubby space underneath. Rather than just stuff the cubbies with junk, I can fill the bins, so everything looks neat, clean, and organized.Five stars and highly recommended for anyone who's looking to organize their stuff. Perfect for art studios, craft rooms, sewing rooms, home offices, bedrooms, etc. They come in several different colors, too, so you can match your decor. I ordered the aqua ones, which is a bold turquoise color. A bit brighter than I was hoping for, but still quite nice. I'm reorganizing my sewing room, so I'll likely be back for more.
