Really rough, I can file my nails on them.
The base is completely flat, with some faint rings from being pressed in the mould.
It's well-made, but was not given a proper quality finish, to save time and money.
At the time, there were a lot of the window-green bubbly glass square plates and chargers from Portmeirion for sale too.
There were only two or three of these massive buckets and I bought two, it was around '00.
