Lots of fun! Mack transforms into a maintenance trailer! This is a trailer that can carry the Mack body and Cars Tomica cars. When the trailer is unfolded, it can hold up to 4 Cars Tomica cars. ⚠️ The outer box is not in good condition. There are tears, dents, and deformations. ※ Batteries not required This is a used item that a child played with. I'm selling it because they've outgrown it. This is a used item that a child has played with, so there may be differences in condition between good and bad. I may have missed peeling stickers or small scratches during my amateur inspection, so please judge the condition from the photos and consider carefully before purchasing.
