This is an aftermarket product imported from overseas. This is a truss rod cover designed for PRS guitars. A shell in the shape of an eagle is inlaid into solid wood, which appears to be rosewood. The exact material of the wood is unknown, so please understand that it's just a "look-alike." This time, I applied an oil finish using Xotic Oil Gel to make the rosewood look more like ebony. I applied 2-3 coats to both the sides and the back. I think the shell's shine is also more distinct. The size is indicated in the image. The thickness is approximately 1.5mm. Although it's a general-purpose item, I will include mounting screws.
