This ink well is ideal for watercolor and ink alike. It has a large basin that can be used for holding ink or water. The basin has a half moon pedestal on the inside, so you can rest wet brushes and let the water or ink drip into the main basin. The handle doubles as a brush rest as well. The lid comes off to reveal a 6-well palette. The basin has a spout on it so you can pour unused ink back into the bottle. So simple yet so versatile! The basin itself measures 4-1/4 inch in diameter and it is 1-3/8 inch deep.
