This is not a stand alone product. You need other Wild Gears sets to use with it. This Gear Set is designed to be a companion set to the Compact or Full Page Gear Sets.
Make your own weird shapes by connecting these 'puzzle piece' segments to make gear toothed shapes for gears to roll gears around.
This gear set is made of interlocking pieces that are arc segments and intersections so that they can be combined to form rings and tracks that gears can be used with to make unique designs. Check out the pictures to see what this looks like.
