Whitmor Drawer Organizers Set of 6

I've long been frustrated with my underwear drawer, because everything gets jumbled together, even when I try to fold neatly and keep things separate. Lately, I've been on an organizational kick, so I decided to give these a try. I'm SO GLAD I did! You get a pack of six organizing boxes, three narrow, two medium, and one large with dividers. They're made of a very thin, flexible plastic that's frosted. It feels rather flimsy, but I suspect it will hold up just fine under normal usage. I used the three narrow organizers for my socks and underwear and the two medium ones for my bras and camisoles. They fit perfectly in my dresser drawer, as if they were made specifically for it. The largest organizer did not fit, but I didn't have anything to use it for, anyway, so I'll put it in another room. The only (minor) downside to these organizers is the fact that they come flat and must be assembled. There are no directions, but it's not difficult to figure out. The ends fold in and you insert the tabs into the slots---easy peasy. I will admit that I'm a bit confused by the slits on the sides of the organizers, though. There are these curved tabs cut into the sides of each one and I can't figure out what they're for. I thought perhaps they interlocked with each other, so you could attach the boxes to each other, but doing so staggers them, so they aren't lined up and will not fit into the drawer. I'm perplexed, but it's really not a major issue. Note that these organizers are sized for dresser drawers, not shallow bathroom or kitchen drawers. They might still fit, but you'd need to measure and make sure, first. Five stars and highly recommended for anyone who wants to get organized. In fact, I wish I'd taken "before" and "after" photos of my drawer, because the difference is profound. I'm a bit OCD and I'm dancing on clouds now that my drawer is so tidy! I can see everything at a glance, no more hunting for things or digging through piles to find what I'm looking for. It's brilliant!
