Ball Track Construction Set

This Ball Track Construction Set from Haba is just the item my puzzle-solving, tower-building, tool-obsessed son would thrive on.
Check out all the fun additions you can use to expand your marble set. Few things make me happier than finding an item I or grandparents can add onto for birthdays and holidays. It sort of makes me feel like I am not getting yet another toy for the closet, but just improving upon a much-loved one!
