Aren't they awesome? Some of the reviews said they weren't quite heavy enough, but I was actually impressed with their heft. This set is a great addition to my office space and keeps my design books tidy. It will act as my stand-in dachshund until I can finally get a real one. If you are interested in purchasing a set of your own, keep an eye on the B&N website, they go on sale fairly often!
And speaking of Design Sponge at Home, it's an absolutely beautiful book with great photos and beautiful design ideas. I've even recommended my boyfriend peruse it to get some ideas for his furniture designs. It's a great read!
