On the very bottom of this blue decanter, there is a little rough area. I don’t believe it to be a crack, but there is a little rough spot. I show it in the last couple of photos. I try to put my finger by it so you can see it upon first Inspection I never even saw it , but I double checked it today and noticed the small rough area. I have three of these beautiful glass decanters. I have a green one listed and then this blue one and then a clear one. They are stunning and Rare! The stoppers at the top have a little plastic around them to fit nice and tight in the neck of the bottle, but that plastic is deteriorating and breaking off. The blue one the plastic around it is not broken off to where I can get water inside the stopper so the stopper looks a little cloudy, but it just needs rinsed out. These bottles will look amazing in someone’s window glass collection. This listing is for the blue bottle.
