These Amberina Cruets were made by Rainbow Glass from the late 1940's-1960's. They have clear pulled back handle and ruby red stoppers. All of which are hand made. The stoppers have a semi-rough pontil and a flat stop on one side, for easy fit. Each cruet stands 6 1/4" tall without stopper and 10 1/2" tall with the stopper.
One of the cruets has 2 index finger size circles in the crackle which my husband says is just the way they crackled. He is most likely right but I did want to picture the anomaly and place an arrow so you can see for yourself. I did not notice the circles until I went to picture them and they do look like the crackle, it is just that they are circles and I always try to be very careful and mention anything that looks different.
