Diamond Magic is a manufacturer of professional car care products, mostly marketed to and through auto dealers. For some time, it had packaged its New Leather Cleaner in a 750-mL PVC bottle and its New Leather Conditioner in a 250-mL PVC bottle, each topped with a trigger sprayer. The new dual-chamber container holds 300-mL of cleaner in one side, topped by a fingertip sprayer, and 150-mL of conditioner in the other side. It is dispensed with a lotion pump. Both dispensers from Emsar (Stratford, CT) fit each side’s 24-410 finish.
