This listing is for the Mindware brand Q-Ba-Maze 2.0 marble run Rails Creator Set toy pictured. It is in good used condition with no missing parts. The box has seen better days, but the instructions, rails, cubes, and 15 metal marbles are all accounted for. This is a fun learning toy with many possibilities. This weighs 1lb 14 oz without a box or packing materials so it can only be bundled with lightweight items from my closet. Thanks for shopping my closet, I ship quickly and pack my orders with care.
