This is an aluminum joint cap for radial pins. The color is glossy black. The size is approximately 5.8cm in total length, approximately 2.2cm in diameter (at the thickest part of the joint), and weighs approximately 45g. Made of aluminum, it has weight unlike resin or wood, but it will firmly protect the butt and shaft. It's almost new, but there are some minor scratches from being used once or twice. Please refrain from purchasing if you are looking for perfection. If you have any questions, please comment.
