Why doesn't my jar of sprinkles weigh exactly 4 or 8 ounces?Updated 3 years ago

Because our sprinkles are all different weights, we use the volume measurement of our 4 & 8 oz jars as a guideline.  Jimmies are lighter than sixlets, and rock sugar is heavier than confetti stars. No matter what the mix, we fill the jars to the brim. In some cases, it will be lighter than 4 or 8 oz and in some cases, a bit heavier.
