Mattel Thingmaker Zoofie Goofies Vintage 1968 Giraffes Hippos Elephants

The heating unit works perfectly. No rust on the heating unit and the cord looks great. Front 'Thingmaker" sticker is peeling a bit on the unit. Comes with 7 molds, the cooling tray, the tool to remove the molds from the hot unit and a small piece with little spikes on it, not sure what the purpose is. No instructions. The goop bottles are empty. The plastic tray has holes/melting/cracks. The box has wear/tape on the corners.
