I have a question: if I have a cube that is not in the museum, but is mass produced, should I still add it?

Also, would lanlan be considered a KO brand? Most of their pzzles are completely new, as far as i know.

Please just send me (or Dave) a pm awith the puzzle in question and I'll answer you. It will also save Andreas a lot of work if we do that first.
We will be happy to help.
