Everyone loves this clay and it will keep your kids busy for hours!  It's easy to bake in any oven at 275 degrees for 5-15 minutes depending on the thickness.  The FULL Kit includes a set of starter tools that help with carving and rolling the clay.  If you already have those tools, just buy the STANDARD clay kit. 
 
Both kits contain the following: 
8 blocks of clay, each a different color
Two sets of multi-sized cookie cutters
One large Pine/Christmas tree shape
 
The FULL Kit adds in the set of carving/rolling tools.
