Nordost Sort Kones BC Model Bronze/Ceramic resonance control devices

Selling set of three Nordost BC Sort Kones (as a set). These bronze/ceramic resonance control devices are the next to the top of Nordost's four levels of Sort Kones. I bought them new from an authorized dealer this past fall and they are in flawless condition (rated them 9 only because they are not brand new). These are seldom seen on the used market. Used in house with no smoking, pets or children. Original packaging--note the boxes in the photo look bleached, but that is due only to reflection from the bright sun in which I took the pictures. The boxes look as new as the Kones themselves. Buyer pays shipping and 3% PayPal.
