I have an unused, unstickered black mf8 Petaminx with an extra center piece replacement just in case that I'd like to sell. Everything seems to turn fine on it. I would prefer a US/Canada buyer as this is quite heavy and expensive to ship. Will consider overseas buyers if they are willing to help with shipping. Might be open to trades but only for an interesting custom Shapeways puzzle or something. Please PM me if you're interested.
