This product is part of the "Project Rock" collection, which was created under the auspices of Dwayne "The Rock" Johnson, who proclaims the message that it doesn't matter what color your skin is, age, where you are from or what you do for a living. The main thing is that no matter what the odds are, you can always achieve something great. It all starts with hard work and what you're willing to put into your hands.
