1. An injection-molded product formed by using:
a nozzle having a nozzle body, an inlet port through which a fluid is introduced, an outlet port through which the fluid is delivered, and a plurality of elements positioned between the inlet port and the outlet port;
natural pellets; and
masterbatches that color the natural pellets,
wherein, the nozzle is configured such that in a condition where the fluid formed from the natural pellets and the masterbatches is applied to the inlet port of the nozzle, fluid is kneaded by the plurality of elements and a rise of an injection pressure of the fluid is suppressed,
wherein, in a color measurement test using a test piece of the injection-molded product in a flat plate shape, a color difference between a first concentration portion and a second concentration portion of the masterbatches with respect to the natural pellets in the test piece of the injection-molded product is not more than 6.5,
wherein, in a tensile test in accordance with ASTM D638 using a test piece of the injection-molded product in a shape of ASTM #4, a tensile breaking elongation of the test piece of the injection-molded product is not less than 40%, and
wherein, in an Izod impact test in accordance with ASTM D256, an Izod impact strength of a test piece of the injection-molded product in a shape of a thickness of 3.2 mm*a width of 12.5 mm*a length of 63.5 mm is not less than 24.5 J/m.
