●Product Background Until the Great Hanshin-Awaji Earthquake 30 years ago, flip-flops made of natural rubber were made in Japan. However, the factory was damaged by the earthquake and went out of business. Along with that, flip-flops made of natural rubber are no longer made in Japan. TSUKUMO wants to make flip-flops made of natural rubber again in Japan someday. We started by looking for a factory, found a factory with still equipment, and reprinted natural rubber flip-flops made in Japan. ●Product Features It is comfortable to wear and sticks to the soles of your feet, and it has cushioning that does not get tired even if you wear it all day. The thong is also made of natural rubber, so it is less likely to hurt.
