visually I like those little square cups very good. They are also very stable, since the glass is quite thick. However, drinking from it is also a bit strange. It is best to drink from a "corner", otherwise it may happen that the coffee lands rather on the shirt than in your mouth.
Unfortunately, they are only a very limited stack, hence to build the best small 3 pyramids. Bearing in mind the price and the problems that one would actually advise against it - I find them but still nice ... :-)
