I contacted the company with my name and address and a photo of the mugs I have and within a few days they had sorted it all out for me. Apparently they had a bad batch that hadn't been glazed properly and mine must have been part of that batch. I am so impressed with the speed and generosity of the company as I received more mugs than I had bought. They arrived this morning and are lovely. They also said that they are posting out two more in January. Amazing customer service
I love them !!
Have a Very Happy Christmas everyone and a Healthy and Happy New Year
