Black Clay Yixing PotFloating Leaves US
This pot has been used before. Low profile and relatively wide opening makes it especially suited to open leaf oolongs and big leaf puer.
These were all sold to me as 90's Factory One pots. I don't have enough experience to say if they are really factory one pots. But I enjoy using them, think they look good, and they brew tea well.
The thing about this era of factory pots is they are made with good clay and function very well. In my experience they can outperform modern pots of three times the price.
