These enamelled cufflinks harken back to the days of World War 2 (WW2). These well-designed cufflinks resemble the bomber planes that were used in the war. I don't know much about military aircraft, but I hear that this design was a very unique and innovative design for the time. Hand painted with hardcoat enamel, these feature store's lifetime guarantee for product workmanship. Dimensions: 1" x 1/2"
