We received a lot of feedback on the "Schubert" bag, which was introduced on TV Tokyo's "World Business Satellite Torema" and became very popular, and we have prepared a large size that can hold a large laptop!
It can be expanded nearly twice as much, and is large enough for a business trip of 4-5 days.
According to a survey conducted around the world, the L size sells about twice as much as the S size.
It is also available at physical stores such as Bic Camera.
