I've been trying to remember where they came from and exactly what they were like. They were not the same bark sort of texture as yours, I think they had some pint glass style panels around the bottom half. They may well have come from a Carrefours supermarket in France.
But basically, they were novelty packaging for supermarket "posh" fruit liqueurs.
I hung onto them for years, but they were far too small for me when I did drink, and of no practical use after I gave up.
They could be used for chocolate pots.
But I'd rather just sit with a spoon and the mixing bowl.
