A single pyrolytic graphite square. The pieces measure about 10mm x 10mm minimum and less than 1mm thick.  Some pieces are slightly larger and what you receive will vary at random.  Pyrolytic graphite has many interesting properties including excellent heat transfer and the ability to levitate over rare earth magnets when properly cut.  The last photo shows a piece levitating.  Please note that no magnets or anything else is included besides the piece of graphite.  The last picture is for reference only.  These pieces are the perfect size for magnetic levitation experiments.
