Puzzle ball ashtray design in vintage metal from the 70s

Modern semi-spherical heavy ashtray made of mirrored metal, transparent glass, white rubber and 4 steel balls. This is surprisingly also an agility puzzle. The object is to place each marble under each cigarette notch. Note that we tried to play with it: it is easy to place 1 or 2 marbles, we did not succeed in placing 3 and it seems impossible to place 4 except by turning the ashtray upside down. The ashtray is in good condition. Diameter: 13 cm. Height: 7.5cm. Weight: 900g.
