After asking the question, I ordered and was very disappointed: the glass is not a part. I mean, not manufactured in one piece but the foot and the cup are manufactured separately and then assembled.
Thus, there is a gap that I do not find attractive, and we saw many on the photo of the article.
Also, my glasses had a vertical stops along the foot, and the bottom was irregular cut (roughly épaisà various parts of the same glass). For these two points, I can not generalize it could be a default (but I doubt it).
I envision them: the same brand, more expensive, which will be finished a little better ...
I did not think to take pictures, but I have returned to Amazon.
