From Royal Global:

The Royal Global adjustable barrel features an innovative patented mechanism combining a premium aged grenadilla wood bore with an all new eco-friendly material exclusive to Royal Global. Many years in development, the material is created from mixing grenadilla dust with strong fibers that result in an almost identical density to grenadilla. This process allows Royal Global to reduce manufacturing waste and create a more durable, crack-resistant product that will last for many years. By manufacturing the top section and bore with grenadilla wood and the base with the new ECO material, the Royal Global adjustable barrel maintains a wooden bore that helps achieve the warm, rich, and vibrant tone that many players prefer. Four indicators milled on the ring allow for easily repeatable adjustments, with marks every .25mm. There is no tenon gap created by pulling out the barrel to lower pitch, allowing for a more resonant, connected sound and reducing the possibility of leaking when adjusting. The length is adjustable from 64mm to 68mm and works for both Bb and A clarinets with "standard" size tenons (Buffet, Selmer Paris, Yamaha, etc.)

Available in:
Silver - Focused, centered sound, resonant
Gold - Powerful, deep sound, with wide range of harmonics
Pink Gold - Darker and more mellow than the gold, "warmer" sound
Black Nickel - Rich, complex, with the most "hold" to the sound - this model designed in collaboration with clarinetist Sergio Bosi.
