The Setsuna Mobile Phone Strap was released in Japan on August 1, 2004 by Kodansha for ￥1,200. It was released as merchandise for Negima's main manga series.
This was released as a handy and decorative strap to cellular phones. It has a wooden base, featuring an imprint of the title of the series and Negi on a broom. The metal is stainless steel. Also attached is a charm of the featured character, in this case being Setsuna Sakurazaki.
This was released as part of a set of nine straps, each featuring various characters. This one was part of the first release and features a slightly more simplified design than those that would be released a few months later.
