The Cello AIR-Case combines elegant aesthetics with a new manufacturing process. This method ensures broad freedom in design, while being even lighter and more firm. The combination depicts a symbiosis of tradition and modernity. By combining the technical aspects with the concise design-shape, the function of this case was born: Higher firmness and better protection from thrust and impact. The basic shape was adapted from the instrument and reduced to the minimum required volume. The musician and his instrument were always in focus of the design process. The outcome is an accurately fitting sheath with a sensual lightness. Following the instrument shape, the aluminium pilaster strip is the significant visual element which generates an enormous recognition value and reflects the sensuality of the instrument.
