 A Gain Scent Bead Story. Jim was at the laundromat when he heard... His ear said, Maracas, senor. But his nose said, Hey, freshest scent ever. Following his nose, Jim found a man pouring a bottle of Gain Scent Beads into the washer. The scent, the freshness. Jim blurted, Sir, your scent Maracas smell amazing. Actually, Jim, most noses call them Gain Scent Beads.
