Celebrate 3.14 the baker way—with pie. The Pi Day coffee mug is a playful choice for bakers who appreciate a good math pun almost as much as a flaky homemade crust. Pour in your favorite coffee while rolling dough, mixing fillings or baking a pie worthy of its own equation. Perfect for Pi Day on March 14th, math teachers who love baking, pie makers, home bakers, cottage bakers and anyone who agrees the tastiest kind of pi comes fresh from the oven.
