Every Cubitec kit contains the ingredients for creating six attached cubes, which can be configured in the fashion most suited to your needs. Available in orange, green and white translucent hollow injection-molded polypropylene, each shelf will hold up to 55 pounds.

I love these! I have the white/translucent in both my office and my home office. There's a myriad of configurations. Issue: the directions are absolutely hilarious- you'll be figuring out assembly yourself.
