Unknown plant pot

I was given this plant pot by a friend (who had it outside her home and I remarked how wonderful it was). It doesn't seem to have any specific makers mark but the pot itself has a striking design and I'm sure a lot of work went into it, so I'm hopeful someone might may be able to tell me more about it.

I'm quite intrigued about the techniques used to make it - the separation between colours seems to look like the outer glaze has been scored through. I have never seen anything like this before.

Any info about the style if not the maker?

Thank you

They are sold in garden centres. I’m not sure where they are made; possibly Thailand or Vietnam

the clean lines are achieved by wax resist technique, this means they are drawn with a wax-like liquid that masks the lines from the glaze then burns off in the firing

Thanks for the info. Much appreciated.
