Mannen Stamp Pad is developed and sold.

In these early days, a stamp pad had to be inked each time it was used. The Mannen stamp pad introduced continuous stamp use without ink replenishing. It was a groundbreaking product, but was not quickly accepted by the public. The company decided to give away the stamp pads as gifts to the police, local government offices, banks, and other public institutions. Their use verified the effectiveness of the new product and sales finally took off. Subsequently, the company, whose name means “orca flag,” was thinking of putting the image of a rising sun on its emblem, but this was reserved for Japan’s national flag and was not considered appropriate, so the orca flag became the company’s emblem.
