Gnu B Grade: Every board we make is handcrafted. Occasionally, we build boards that don&';t quite live up to our strict cosmetic quality standards. We call these B-grade beauties. B-grades have mild cosmetic imperfections that do not impact the board structure, performance or longevity. We cant guarantee the specific cosmetic oddity that you will be getting, but we can guarantee the amazing price and handcrafted performance.
