Vintage Empoli Italy Green Blown Glass Cruets Oil & Vinegar Mid Century

This is a pair of vintage blown glass cruets made in a striking emerald green colour. Ive seen these identified as having been made in Empoli, Italy during the 1960s, but I dont have a definitive source, so Ill just say that they are beautiful quality glass cruets. Each has a polished pontil mark on the underside (see last close-up photo), which, along with the small differences between the two, are indicative of individually hand blown glass pieces. Both are in excellent condition with no chips, cracks or wear, but one had contained old balsamic vinegar in it, which I cleaned out, but I missed a tiny touch - it just needs a further cleaning to eliminate that tiny bit of residue. Each measures 5 1/4 in height including its stopper and 4 to the top of the lip without the stopper.
Lovely smooth appearance to the glass - striking colour!
