When I saw the opportunity to review the Purex Fels-Naptha Laundry Bar, I jumped at the chance and quickly signed up. I am so thrilled for the chance to write about a product that I already use. I first started making my own laundry soap about four years ago. I had no idea what Fels-Naptha was either. I received a sample of Purex Fels-Naptha Laundry Bar in exchange for my honest opinion.
