These 11oz mugs are customized with your Birth Flower and constellation. These have a pop of color, and can be customized. Dishwasher and microwave safe. There are 48 combinations of mugs available, featuring two flowers and two constellations for each month. While we do our best to ensure all pictures represent the true colors on each piece, due to variations of computer monitors and phone screens, item colors may look slightly different in person.
