In the past, samurai contracts were sealed with keppan, a thumbprint sealed with the warrior’s own blood, cut by his own blade. The vermillion color of the Japanese seal comes from the blood of these keppan to represent the significance of their seal. There are two main types of vermillion inkpad: the common sponge-type inkpad and premium inkpads made from kneaded vermillion.
The sponge type is the most commonly used ink in Japan for sealing. It is inexpensive, easy-to-use and long-lasting. We offer sponge inkpads in three different sizes.
