The Golfer's Mug is the perfect gift for anyone who has slogged their way through 18 grueling holes of golf and enjoyed it. This traditional coffee mug features a flattened side which makes it absolutely perfect for living room putting. Unlike a round glass or cup, the Golfer's Mug doesn't spin away when a ball hits it. Plus, it's ceramic, so it's microwave and dishwasher friendly. Capacity of 13.5 oz. Note: a golf ball is not included. http://www.vat19.com/dvds/golfers-ceramic-putting-drinking-mug.cfm?adid=youtube
