A reserve price is the minimum price the seller will accept. This price is hidden from bidders. To win, a bidder must have the highest bid and have met or exceeded the reserve price.
The Trombone you are bidding on shows signs of wear but plays great! The mouthpiece is in great condition and valves all work properly. Few dings and scuffs. Great for a student and yes that's my cat in the 3rd picture. Buyer pays shipping. Good luck!
