This is a small device for joining boxes together.
get the Kids to gather all the old used boxes, (cereal, tissue boxes etc)
push the "Box Builder" into the side allowing the cone shaped spikes to grip the box. then push another box onto the other side of the "Box Builder" and in no time at all you can build anything you can imagine.
build robots, castles, cars, planes, dragons.
when the kids are finished just remove the "Box Builder" and recycle the boxes.
