I have an glazed rectangle that might work, I used it once for a shimpaku, so it will work with conifers.
It has a nice patina and it's 5-6 years old.
17 1/2"x 13 1/2" x 4 1/2"
I have an unglazed rectangle that's hand built but without a chops, it's smaller but it has a small crack that would have to be repaired.
