About the design
Wave Box is an evolution of Stratum and in fact an early piece of this range was called Stratum Atlantic Storm. From summer 2014 to February 2015 the range was called Sea Box as can be seen from the label in the picture below. It was then renamed Wave Box. It is available fumed (matt) or unfumed (shiny) in just one colourway in many shapes. It was not included in the first official catalogue of studio designs released in October 2014.
