Mid-century vintage glass decanter, amberina orange glass mod square bottle

We love the flame orange color on this amberina glass decanter bottle! It has a plastic fitter to hold the glass stopper snugly in place, so it's a practical piece for everyday use as well as a mid-century mod collectible piece.

This bottle is 10 1/2" tall to the top of the stopper, and both the glass and the plastic fitter are in very good condition. This isn't marked as all that we could see, possibly Italian?
