First versions were made ​​of hard rubber, and there are also overlay versions in gold rolled metal. The initial production was certainly very small, since have been found handwritten guarantee scraps dated 1933, signed individually by Dante Zerollo. This first production was followed by new celluloid versions, made ​​in beautiful marbled colors or wood grain, and with extremely refined working as a peculiar spiral faceting.
