This robust little mug holds 350ml of liquid be it tea, coffee or any other drink you might want. Ideal for the outdoors whether on a picnic, hiking or at a football match, these ever popular mug types are based on the "Tinny" once used by "The Jolly Swagman" in the Australian Outback. In truth the Jolly Swagmen weren't always jolly but often a little rough around the edges !!!!
