Hubelino Mega Building Box Set with Marble Run Pieces

Big is an understatement here. The Hubelino Mega Building Box Set packs 585 pieces into one sturdy box with a handle, so young architects and experienced builders can take on serious construction projects. Six different extensions, plenty of building blocks, run elements, base plates, marbles and special components all come together in a single set.

Build detailed structures or lay out a full race track — the instruction book offers three giant assembly ideas to get started. Kids aged 4 and up can dive in, and budding engineers aged 8-12 tend to get especially absorbed. Standard bricks from other manufacturers fit right in.
