Thank you very much for viewing. As the title says, this is likely a set of 4 American car mini-cars released by Kyosho. I received these as a gift, so the details are unknown, but it seems the mini-cars and the accompanying cards are different. There is only one box, and the rest is as shown in the photos. Please note that these are not unopened, and have been opened. Also, please refrain from purchasing if you are concerned, as these have been stored at home. The contents are as follows: Lotus Europa S1 Red (Lotus Europa) Lotus Europa S1 Yellow (Lotus Europa) Pontiac Firebird TRANS-AM Red (Pontiac Firebird TRANS-AM) Pontiac Firebird TRANS-AM Yellow (Pontiac Firebird TRANS-AM) Thank you for your consideration.
