Tenshi-no-hane, meaning feather of angels, is a famous trademark of the lightest randoseru, a kind of schoolchild's satchels Japanese children usually have, produced by Seiban. In 2003, that got to be in the Guinness Book as the lightest and toughest randoseru in the world. It is surprisingly that the randoseru totally weights 640 gram. Seiban, established in Tatsuno-shi, Hyogo, is still a leading maker of randoseru in Japan.
