When designing the Soft cases we have considered not only size and weight of the instruments but also the musicians needs. The new SIZE C is specifically designed for the Numa X Piano GT. That's why it fits so well, like a tailor-made suit. What distinguishes the C size above all are the two pairs of wheels that allow to transport the unit effortlessly. Soft cases are available for Numa Compact 2, Numa Compact 2x, Numa X Piano GT, Numa X Piano 88, SL88 Grand, SL88 Studio.
