Meat Marinade Injector By Rockaz Kitchenware Keeps even the driest meats moist during grilling and smoking. The 2.5-inch stainless steel injector needle unscrews for easy washing. The wide nozzle resists clogging. Shortens marinade times and boosts the flavor. One side benefit of using this marinade injector is that the sharp needles cut meat fibers, allowing you to tenderize otherwise tough cuts of meat.
