Thank you for viewing. I would like to deliver this item to someone who appreciates its value, so I am not considering a significant price reduction. This is a 46mm Ki-Arji 2 with copper plating (aeris) in rhodium aurum from around 2019, which differs from the current model. The yellow paint on the lower part of the tube is a characteristic of the older model. The tone, pitch, and resonance are all far superior to the current rhodium aurum model. The reasons for the difference in quality compared to the current model include the different shape and thickness of the Ki-Arji tubes at the time (approximately between the thickness of the current normal and Vibra models) and the different plating method used for rhodium aurum at the time. I have carefully stored it without using it to this day. (There is some discoloration due to oxidation of the copper plating. In my experience, this does not affect the quality.)
