I agree. To be honest this ones been bothering me, which is why I've delayed posting.
My thoughts run along the lines of China!! Had I not seen a number of similar items in TK Maxx in the summer and autumn of last year it would not have occured to me.
The bright colour on the inside with a sort of white 'halo' running around it is very remminiscent of those pieces. Yet the controlled colour scheme within the outer casing seems a little too sophisticated. The ones I saw ranged from badly made with badly executed colour schemes through to well made and well coloured. Most had small "Made in China" labels on a flat base.
I realise that there is a time difference, but TK Maxx's stock is generally from old ranges. Whilst this all proves nothing, it maybe an area to check out.
Good luck, Nigel
