The attention to detail in the finish and overall build of this cup is fantastic.
My only minor complaint is the lid has nothing to hold it in place, and needs to be sized slightly larger in diameter. I can figure out a compromise to make that work at least to my satisfaction.
It would be a very minor thing to modify the design prior to firing so that the lid sits properly with minimal chances of shifting..
It's a nice cup and makes a good gift for any who appreciate functional art. I have gifted a few mugs from here already.
For what it's worth; I am a person who appreciates art and formerly made ceramic items (plates & cups) myself, I am friends with people who make ceramics for a living.
