The Design-It Activity Pack lets young engineers create their own, unique train cars. Use the included stickers, or other at-home craft items such as paint, markers and more to create personalized cargo cars for your Wooden Railway Collection. The classic, real wood construction of the Thomas Wooden Railway is not only beautifully crafted, it's built to stand up to the rigors of preschooler play, teach valuable lessons about teamwork, cooperation, sharing and friendship and will deliver year and year of classic play, long after other toys have been forgotten, discarded or outgrown.
