With Sonic's Nobirura, you have two rulers in one: it is a 16 cm (6.3 inches) ruler that extends to become a 30 cm (11.8 inches) ruler. In its compact 16 cm form, the ruler conveniently fits in your pencil case. The clip lets you clip it to your notebook and papers, and it serves as a handy bookmark. Once extended to its long form, the ruler is long enough to draw straight vertical lines down an A4-size page.
