Shachihata is a Japanese ink manufacturer that was first established in Nagoya, Japan in 1925. This legacy ink brand continues to see worldwide popularity today, serving the needs of stampers worldwide. The 24 color "Iromoyo" ink pad series are formulated with oil-based pigment ink, giving the colors vibrance and lightfastness. The ink pad surface is slightly curved, allowing the full surface of the stamp to make contact with the ink pad.
