Plarail Thunderbirds 6-Car Set Cars can be connected for play. Great for collections or as a children's toy. Overall signs of use, with some yellowing. Cleaned with alcohol wipes. There are stains and scratches (see photos 6-8). Slight tilt (photo 1, middle car on the left). I don't have batteries on hand, so I haven't been able to confirm the operation. Please be aware that it may not work even with batteries, so please refrain from purchasing if you are concerned. You can still play with it by moving it by hand even without batteries.
