The designs on Camilla's mugs are taken from her 3 dimensional ceramic wall art. Each little square transfer is an optical illusion in itself. When put together they create a unique geometric design. The transfers are applied randomly by Camilla to fine bone china mugs which are made in Stoke on Trent, UK. No two mugs are identical, each one is slightly different. They are microwave & dishwasher safe. Save by buying a set!
