Classic Mug, 325 ml
I have ordered from zazzle before and it was perfect. This time the mug has arrived in great time but the mug has rubbed on the box and has affected the image, I was hoping to get in touch with the creator but can’t seem to find a way of contacting them. We would love another sent out maybe wrapped in bubble wrap to protect the image. Would love to hear back from the creator. Kind regards, Lisa.
