Shape retention A4 flat file compatible "E-QBU Structure" By widening the inner width, the outer width of the randoseru becomes "too large". The "coloris series" uses a molding machine dedicated to the E-QBU structure, and while maintaining the outer width, it expands the inner width to 23.5cm while maintaining strength, allowing it to firmly accommodate A4 flat files. The large gusset part, where textbooks are placed, is considered the most vulnerable part of the randoseru. The "coloris series" is equipped with shape-correcting resin in the large gusset part. Furthermore, a steel core is built into the center. The original shape correction processing "Shikkari-kun" firmly protects the randoseru from deformation and bending. It uses a Fit-chan back panel that fits the back.
