Refill Packs have the same amount of dye in them as comes with the jars. You can refill our 4 ounce jars or provide your own. Just add dye to 4 ounces of hot water. We suggest bottled water. You can also mix a small amount of the powdered dye with salt in a small salt shaker. (We sell those too!) Sprinkle on a wet gourd for a neat effect.
