A Zero Japan handmade ceramic small coffee dripper. The key trait to this dripper is a concave and 2 spout holes carefully calculated so the drip will concentrate to the center. Because there are 2 windows near the base part of the dripper so that users can confirm the amount of the drip and prevent leakage, you can look inside the cup and know the exact amount of coffee in the cup. This is extremely useful. The inside of the small dripper is 2-1/4 inches deep x 3 inches wide x 3-1/2 inches long at the top and tapers down towards the base at a 45 degree angle. It holds about a 1/2 cup of liquid at a time. Start with a medium grind (coarse sand) and a slow application of water that doesn't pool on the top for best results.
