Anyone familiar with Enzo Mari's art will recognise his principles applied in the design of the Java container. The top is semi transparent, so one can see what's inside. Mari would have also been interested in how the circular lid pivots and how it relates visually to the smaller circle of the container seen through it.
This the first edition, only produced for a short period. It is the high version, which makes it an even more rare find. It's condition is still excellent.
