With the Hot Wheels Track Builder Straight Track Pack (ref. JDW41), children aged 3 to 7 can extend and customize their tracks as they please. These orange plastic straight sections snap together to form straightaways that integrate directly with existing compatible Hot Wheels tracks. Lightweight (105g) and easy to combine, they invite kids to rethink their track layout during every play session. Assembly, which must be performed by an adult, becomes a shared bonding moment before the race begins. A simple and effective extension to enhance a miniature world that’s already well underway.
