Mattel Disney Pixar CARS Diecast: Snot Rod with Flames Variant
If you collect variants, Snot Rod with Flames is a definite production variant. It seems the first production ones were transparent at the base and opaque at the top of flames (foreground one).
Yes, this saves some money as the only way to make it opaque is to apply some paint towards the top after molding the transparent “flame.” So, it seems the current ones are only “transparent.”
The clue is the current ones do not have a production date under the CAR but is stamped on the card.
