Soul Rebel Mojo Workin' T-Shirt. Soul Rebel has been making noise for the last couple of years now. Growing from a small collectors line to a full fledged brand. Style, character and comfort are paramount. These values are reflected in each garment that Soul Rebel produces. Our t-shirts are made from ultra soft, 100% machine washable cotton. On the front of this shirt is a keyboard and it says "Soul Rebel got the mojo workin'"
