Butter mold from the 60s. Bears mentions on the back of " Coquillor - Glace ". Missing the original box. Approximate dimensions: 16 cm long x 14.5 cm wide x 4 cm high
Instructions: remove the base, turn the top over and fill with butter up to about halfway. Put the tray back on the base, taking care to turn it over and press lightly on the edges. The butter will then come out of the holes in the form of pretty jagged chips.
