Mustard is taking the term ‘shot glass’ literally with the 12 Gauge Shot Glasses. Made of plastic, the shot glasses looks like shotgun shell complete with the gold color knob. The 12 Gague Shot Glasses comes in a set of 4 and for you UK folks, it’ll set you back £13.00 via Mustard. For us American folks, it’ll be $15 at Amazon. Please don’t trying loaded this in your shotgun. I’m sure your gun won’t appreciate the alcohol.
