Fexio is a portable and solar powered paper-packaged radio, it only receives one fixed FM channel. One side is the speaker and the other side is solar cell, if you want to use it, just let it under the sunshine or light. Want to close it, take it back to your wallet. Cool and simple concept, I love it! Designed by Wu Kun-chia, Wang Shih-ju, Chen Ming-daw & Liou Chang-ho
