The label inside the sound hole is made of "Stainless Steel". The Rebel logo was inspired by the Japanese kamon or japanese emblems or crests used to identify an individual or family. It's been around for almost 1,000 years.
The Rebel Logo "The Triforce" represents Power, Wisdom and Courage. We sincerely hope that the instrument will bring happiness along with the three powers to those who have played or listened to it.
