Set of 5 designer ashtrays by Isamu Kenmochi, 1960, original case.

Elegant set of 5 stackable ashtrays “Tower Ashtray”, attributed to Japanese designer Isamu Kenmochi, dating from the late 1960s. This iconic model of modernist design is distinguished by its minimalist cylindrical shape with a chrome finish, combined with colourful melamine interiors (orange, green, blue…), typical of the “space age” aesthetic. The ashtrays fit perfectly together to form a compact tower, both functional and highly decorative. Particularly interesting example with its original storage tube, marked “Tower Ash-Tray”. The underside of each piece bears the inscription “PAT. PEND. 4018039”, corresponding to the early productions of this model from the late 1960s. Condition: Very good overall condition. Shiny chrome, with no notable oxidation. Colourful interiors in excellent condition. Original box with signs of use (see photos). Dimensions: Diameter of the ashtrays: 7.3 cm. Height of an ashtray: approximately 3 cm. Height of the box: 17.5 cm. Diameter of the box: 8 cm.
