In collaboration with Cultural Lab., a lab of students from Bunka Fashion College, we created the calculator with the concept "The Choice is YOURS", which expresses multi-faceted values through the design. Each calculator is unique, the body is colored with marble patterns where no two are the same. In addition, delicate fonts are used to bring out a cool feel. The original package has a delicate gradation. ※ Patterns and colors of each calculator are different due to marble pattern. ※ The marble design creates colors and designs unique to each calculator.
