I am in need of TWO all original 18” Lava brand “The Wave” Machines for a display in a museum in Italy. I am willing to pay $500 shipped EACH. They MUST have the original vessel with the rubber plug in the end cap and a black base. This is time sensitive and my offer is only valid until Tuesday and they must ship same day. Please send me an email at email@example.com if you have one or two of these units.
