Oyster Shell Natural Rubber Flip Flops – Made in Japan

From Osaka Bay to your feet.

These flip flops are made using natural rubber blended with 5% recycled oyster shells collected from Osaka Bay, in cooperation with Hannan City, Osaka.

Oyster shells, once discarded as waste, are carefully processed and reborn as part of the sole material. This not only reduces environmental impact but also gives the sandals a unique texture and natural character.

Crafted in one of Japan’s oldest flip-flop factories, each pair reflects traditional manufacturing methods that have continued since the 1950s.

The straps are made from natural rubber in a classic brown color, and the soles are designed to provide soft cushioning and long-lasting comfort.

Simple, durable, and meaningful.
These are not just flip flops — they are a step toward sustainability.
