mine were flat wheel like in design ....fab design, the recipients both took a few minutes to work out how to stand them up and put the stopper in and then realise what they were. I love them. The two I had were turquoise with that rough finish and a deep cerise pink again with a satin finish. I just assumed I would find another to buy for myself but haven't come across one yet (apart from online).
They are one of those pieces that has that certain something - they do make perfect and unusual pressies.
