A beach sandal derived from a plant made with 100% of natural rubbers brought up in Thailand. Of the natural rubber fluffy softly; wear it, and is very comfortable for a feeling. I dismantle it by air and power of the light of the sun naturally, and the natural rubber made from sap returns to soil. Do not become the drifting ashore garbage by any chance even if is carried off in the sea by a wave; biological decomposition. The greenhouse gas does not increase the garbage on the earth, too either. It is the beach sandal which is kind to the environment where we live in. A clog thong part "is natural rubber same color natural rubber" not to use dye and the mixture for at all. The texture that is simple in natural rubber original nature is attractive. The logo tag of kaisou is in the clog thong part, too.
