Jack Daniels Shot Glass called Double Barrel.   This comes w/ a card of authenticity.  It is made of stainless steel with the name on the front. It is engraved w/ the initials PSG which could be buffed off and re-engraved or left plain. It is approx. 3.5" tall.  We never used this as a glass but was used for display purposes only. 

Comes w/ it's original box from Jack Daniels

Thanks for looking
