The kit actually comes with four separate boxes one of which is thermally insulated. It's also providing safety gloves for handling the procedure of packaging the device because it says “some individuals might be sensitive to the ceramic fiber paper lining the Recovery Box.” A document listing all of the steps one needs to take complete with pictures is also included. The accompanying note also contains an apology from Samsung which reads: “Safety is always our highest priority. We realize that we did not meet the standards of excellence that you expect and deserve with the Note7. For that, we sincerely apologize.”
Samsung also mentions in the document that the return package can only be sent back using ground shipping as it will not be shipped by air due to its tendency to explode. The company appears to be taking the return process very seriously and rightly so, it's not like Samsung hasn't lost enough consumer confidence already.
