These days, it's easy being green. And stylish, too.

In honor of Earth Day (Wednesday, April 22), the ShopBlog will host a weeklong celebration of favorite "green" items. Why blog, you may ask? Well, it's paper-free, of course!

Today's cool items, his and hers key rings made of recycled milk jugs, comes from Zanisa.com [1], an online retailer that specializes in sustainable yet elegant gifts. Think Red Envelope -- only green.

I'm a fan of the jewelry -- the pottery-shard bracelet below is on my wish list. But at $6, you can't go wrong with the key chains -- unless they're holding the keys to a tank-size SUV.
