Harley-Davidson® Willie G Skull Coasters. Who would have guessed that Willie G’s skull logo contribution to the Motor Company would one day become as recognizable as the Olympic Rings logo. Today, you’ll find it on Harley® motorcycle accessory parts, on clothing, tin signs - just about everything, and it’s everywhere, including barware. These Willie G Skull coasters act like mini beverage mats for your glass. Made with a no-slip, contoured rubber, the construction of these coasters protects your furniture while collecting the drips and spills. These coasters are 4-inches in diameter. They come as a set of 4. Manufactured under Harley-Davidson® license by Ace Branded Products.
