 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.
