This costs 2,700 yen, about $24 at the time of writing. It will become available on July 29th, the day Dragon Quest XI releases in Japan.

With services like WhiteRabbit, you can purchase from the SQEX e-Store even if you dont live in Japan :p (But their services can get quite expensive, so watch out).
