A fun mug in Chartreuse Green with our signature speech bubble which reads "Bugger Off I'm Working". Our mugs are handcrafted in small batches and fired in Stoke-on-Trent, the birthplace of British ceramics for over 300 years. This kiln-fired process gives them a glossy, durable finish and vibrant colour. Made from premium quality bone china, with a spacious handle for ultimate tea-supping comfort and boxed in a quality kraft gift box for easy wrapping and safe posting.
