The ones I refer to are thin 12x16" poly sheets, very flexible, not the ~1/4 
or so boards.  These look to be about as thick as, say, 5 or so sheets of 
regular sheet poly stacked would be.  Should easily cut to size with 
scissors.  They really remind me of the laminated placemats you see in 
tourist traps...
