Review on Double Wall Espresso Cups Set by Jeff Callier

These were lovely little mugs that came in a nice box with a note as they appear to be from a small company. They seemed a bit fragile and I noticed that the cups are a bit different in size as they are mouth blown. There was a small dot/circle on the bottom of each double wall jar, but as it was advised that they could be washed in the dishwasher I have regularly placed them on the top rack of the dishwasher. After the third or fourth time in one of the classrooms there was some water between two walls, apparently through a small hole in the floor. This was disappointing as they were good quality glasses suitable for making espresso. From now on, all I have to do is hand wash the other three thoroughly.
