I love organizing things. Therefore, I love containers. A few years ago I fell in love with these Really Useful Boxes. They're made in England.
I found them on sale at Office Depot and went a little crazy. I think the prices have gone up since I bought them a few years ago.
I use them to store all sorts of things from paints to CDs to wires. I have all our trip DVDs backed up and organized in the larger size containers. They're supposed to be really strong. I really like the colors. The only thing that worries me is that in Hawaii, the salt air tends to break down a lot of plastic. So far, these have held up nicely. It remains to be seen if it will stay wonderful 10 years from now, but I'll let you know.
