Despite its name, the Black and Blue won't put a hurting on your wallet or the planet.  Made of about 99% recycled materials, the B&B tumbler is designed with the environment in mind.  But price isn't sacrificed to make it that way.  In fact it is less expensive than many compost tumblers.  And you have a choice in color (Blue or White depending on availability) which isn't often seen with composters.  If you're looking for a tumbler that benefits everyone, the Black and Blue is the choice for you.
