Prairie Chick’s ‘Let That Shit Go Mug’ in white says it how you really feel sometimes! These enamel-look mugs are made of dishwasher-safe, microwave-safe ceramic. Each holds a hefty 15 oz of your favourite Cupper’s coffee. We love the entire Prairie Chick’s collection of mugs in all their pastel blue, green, pink and white. They’d look great in any cupboard and on any table. Best of all, they’re made right here in Alberta!
