The Henna Series has been a staple in the Luna line since its inception, with the laser-etched Oasis design featured on the back of the t-shirt. This T is a testament to the many intricate designs that make Luna acoustics so unique. For this shirt, it's business in the front with the logo, and party in the back with the Henna Oasis display. To understand the thought-process behind Luna acoustic guitars is to understand and appreciate world culture, nature, and art.
