The slot cars within are 1:32 scale in size which is approximately about five or six inches in length. They and the other contents enclosed in the collector box are new in the factory original package and have not been professionally graded. The collector box has never been opened and itself is enlosed in a plastic bag taped by the manufacturer; therefore, we are unable to attest to condition of the contents within. We can say that the collector box itself has no visible dents, scars or holes. These electric racing slot cars operate on most readily available 1:32 scale slot car race track systems and are most commonly used on Scalextric 1:32 race tracks in the U.S. Contact your race track manufacturer to confirm this brand of slot car will work with your brand of track. This slot car edition is only available through the hobby market industry. A very nice set. See more.
