Fun stamps, RiraRira Hanko.


Let's create a chain of happiness from a small world!

By hand-carving erasers with wonderful designs and production processes, a unique artistic world and design are completed by artist RiraRira, distinct from digital drawings. Each design is One-of-a-kind.

We conceive, design, manufacture, and commercialize products, managing the entire process from the idea to sales. Ideas are quickly turned into products. We have created over 1500 types of works so far, also sold in Loft and Hands stores.

Rubber stamps that utilize traditional Japanese seal-making techniques.

Our Team

From planning and operations to sales and shipping, we operate with a small team. All of our staff are women who are currently raising children.
