This Shotgun Shell Thermos is just as badass as it is useful. It holds 25 oz hot or cold in the double wall, vacuum insulated container made of rust proof 18/8 stainless steel. The top is engraved to really top off the shotgun shell appearance and is easy to open and close with one touch. It also comes with a 1 year warranty so you can really put it through the ringer. Get one on Amazon for $35 in back, green or red.
