Two college friends, Gwen Weinberg and Anita Nadelson, started Seattle's Three by Three over 10 years ago. Their product line has been evolving ever since, and it's been written up everywhere from Real Simple to Domino to Living Etc.
Three by Three's products includes home, office, and school products. They're practical and useful, with geometric lines and bright colors. Plus, they're affordable. While they may not be quite as inexpensive as similar plain old metal products sold elsewhere, they're a lot more fun.
We blogged their magnetic strip here. We have an orange one, and it really pops on the white wall of our office.
i have the magnetic strip and circle in my office and they are well used and definitely loved!
Also sold at Target.
