A great new kitchen tool

Can you guess what this is for?  It is approximately 4 inches square, two layers of smooth stainless steel rings.

It is a cast iron scrubber!  And it works great.  I have quite a few cast iron pans in my kitchen.  It does a fantastic job of quickly removing stuck on food and oil.  And it goes right in the dishwasher. . . unlike my cast iron!

I found it in Cook's World here in Rochester, a quality kitchen store.  I had never heard of it before and wondered if it was worth the hype.  It is!

I run it under the kitchen faucet when I'm done with it, then dry it with paper towels and hang it to dry completely.
