Unfortunately, flawed blown

The glasses were delivered very well and securely packed in 3 nested boxes, so that during transport absolutely nothing could go wrong.

Here are the 6 ordered glasses at 3 glasses very strong, and emerged with 2 glasses slight asymmetries in blowing the glasses. The bottom of the glass goblets is not uniformly formed, but on one side substantially thicker.
This creates a very strange weight distribution of the glasses, which can be determined easily even when taking into their own hands. Taking the glasses flat on a table, the glasses begin to roll into your focus and then to lie there.
Over a glass of the foot is also running at a slight angle.

Have the glasses looked before ordering at Amazon at the nearby department store and there can not detect such an error. Therefore suspect an error in a production batch.

Otherwise I like the glasses very well.

For no-name glasses might just about acceptable, from a brand manufacturer as Leonardo I expect another quality.

Glasses go back.
