This Magnatiles Cars 2-piece expansion set adds two magnetic chassis with smooth-rolling wheels (one yellow, one blue) to turn construction tiles into moving vehicles. The magnetic wheel bases work as standalone push-along cars or attach to MAGNA-TILES magnetic building tiles to create cars, trucks, campers, fire engines and larger creations. This vehicle playset encourages hands-on STEM learning, spatial reasoning and open-ended creative play. This set pairs with MAGNA-TILES XTRAS Roads and other tile collections for track-driven fun, and the reusable packaging doubles as a ramp for extra play options. Contents: 1 yellow chassis with wheels and 1 blue chassis with wheels; suitable for ages 3+.
