Duro Dubl Life flat-bottom SOS (self-opening style) brown kraft grocery bag, sold by the bundle of 500. The square-bottom design stands upright on the bagging counter so checkers can pack hands-free, and gusseted sides expand to hold bulkier items. Built for supermarket checkout, hardware-store counters, foodservice takeout, farmstands, and produce stalls.
