If you don’t know its decaf it won’t hurt you! The mug is hand-stamped with the words “ignorance is bliss” in a retro typewriter font. This mug was designed by Keith Brymer Jones right here in the UK. You might recognise Keith from BBC’s Great Pottery Throw Down where he was the tall emotional judge. Keith started out his pottery career over 30 years ago as a production potter in a studio in Highgate. This is where Keith first started to develop the Word Range and bring the products to life. All products in the Word Range are crafted using super white porcelain. All products in the Word Range are also dishwasher and microwave safe making them practical in any modern home.
