Query: Works for my espresso machine

This frothing cup was exactly what I needed. I have a smaller espresso machine, that I love. The only downside is that it has a short frothing spout. I needed a small cup and found this one. It is the perfect height and makes enough for one cup of milk. It could be a little bit bigger, but for the machine it works very well. It seems like a good quality cup too. It isn't cheaply made.
