Each Market Refill Bag fills one of my larger grinders completely. Depending on the blend they are approximately 3 ounces or 3/4 cup. It will fill my smaller market trio mills twice. This is double my old refill tube size. Snip the tip of the cone shaped bag to use it like a funnel. These come filled with one of my signature 100% natural Farmer’s Market blends.
