Technically, at a capacity of 25 oz, Stansport’s 12 Gauge Shotshell Thermal Bottle is quite a bit larger than an actual 12 Gauge shotshell, but I’m just being nitpicky. Made of BPA-free 18-8 stainless steel, insulated with double wall construction, this thermal bottle keeps hot liquids hot and cold liquids cold for up to 24 hours. Also available in green, because that’s a color shotshells come in.
