Coasters in your fridge?

I recently stumbled across a very fun and ingenious product...a fridge coaster!

These are a cardboard-like mat that goes on your refrigerator shelves or in the drawers. They are absorbent in case you spill anything and they can be easily switched out if they get too gross. Plus, there are lots of fun styles and colors to choose from.

Coasters for your refrigerator...what will they think of next?
