The NASCAR 88 Amp Energy Transporter Building Set has 250+ K'NEX bricks, rods, connectors, as well as wheels for push play. Once built, truck measures approximately 23-inch in length. And with a trailer big enough to fit two cars (sold separately) inside, your child can put their Dale Jr. K'NEXman in the driver's seat and head to the track. Custom parts, sponsor logos and color schemes ensure that these rigs resemble the real thing. This kid's building set includes official NASCAR hologram, with step-by-step building instructions inside.
