This Oystercatcher mug is hand decorated in the Emma Bridgewater factory where I bought it on my last trip. The factory is in Stoke-On-Trent, Staffordshire, England. The mug measures 3.75 inches by 3.25 inches in diameter. The Oystercatcher mug is a 1/2 pint mug and is part of the Birds line. It is a really attractive design of the oystercatcher and a very charming & decorative piece by a wonderful potter. Shipping in the US by USPS priority insured with tracking is $9.50.
