Children's Play Cube  $99

This is about 2' x 2'.  It's one of those cubes where you move beads from one side of the wire to the other, and other moving spinning features.  

I have found that 30-something guys find this as interesting as 4 year old girls...

It is excellent craftsmanship. Heavy duty and made of plywood.

It orignally cost $600 when new.  It's great for an office or showroom where customers bring their kids and need something while they wait.

$99.00
