Pair Of St Louis Decanters, Cleo Model

This pair of Saint-Louis Cleo crystal decanters represents a high-end production from the crystalworks, established around 1903.
The Cleo design is recognizable by its engraved Louis XV-style arabesques, refined facets, and hand-blown and then hand-engraved construction.

The Cleo model was manufactured for over a century, until the 2010s.
Based on the shape and quality of the crystal, these are likely:

either liqueur decanters,

or wine coolers or tableware.
