It seems that new reports of exploding Samsung Galaxy Note 7's are coming in every day now, and it's got to the point where Samsung have had to halt sales completely.
To facilitate these returns, Samsung has been sending out "return kits" to Note 7 users, and it certainly seems that no expense was spared with these thermal, heat-insulated, fireproof boxes - someone doesn't want any more lawsuits.
The return kit consists if a static shield for the phone, which would be placed in a phone replacement box and then an inner box, and finally a thermal-protective box. The package as a whole can only be transferred by land vehicles - Samsung aren't taking any risks here.
