Ever notice that walnuts look like little brains? Pretty cool. What's more impressive is that their shells work as a natural abrasive to scrub surfaces without scratching. Now that's smart. Walnut shells have serious scrubbing power but that doesn't help if you're allergic to nuts. Not to worry, these pads won't cause a reaction.
