Say hello to our "Fierce Female Mug!" A fierce female is someone who wants to better herself and the world around her! Think of Beyonce who is fierce everyday! Perfect for a gift, this fierce mug is perfect for any fierce female you know. These travel mugs are made from stainless steel, and have a permanent image. Even though these are deemed top rack dishwasher safe, we recommend that you hand wash these to leave a lasting effect and to avoid any rusting if cups are left in the dishwasher.
