Redesigned parts and tools make it easier than ever for kids to build their creations! Nuts snap and lock right onto parts; bolts hold pieces together for easy building!
As kids piece together builds, they'll feel just like real engineers! As they gain confidence with every build, kids can disassemble and invent their own creations!
