The Cube of Fidgeting!  Keep your fingers busy, releive the stresses of dungeon mastering!  In the shape of six-sided dice, this far more entertaining than a spinner!
 
This is a new product, and to be honest I didn't think it was all that great when I first picked it up.  But now ... geez, I can't stop folding it infinetly and getting in a rhythm.  Even people at work want to borrow it!
 
The cracked texture is really cool, too!  It's like a combination of dragon skin and lava!
 
Comes in a free velvet bag!
