It is the Purex® Fels-Naptha Laundry Bar. I was lucky enough to be chosen to review. *Purex® provided me with a sample of Purex® Fels-Naptha Laundry Bar in exchange for a product review. As always, opinions expressed here are my own and always will be.* Fels-Naptha Laundry Bar has been around since 1894, that's 119 years. That tells me right there that it works, or else it wouldn't have survived so long. I like that this is very inexpensive to purchase and would last a very long time. It does have an odor, but it is not unpleasant....
