Thank you for viewing. This set includes one tray and a basic set of 6 items: tweezers, a filling instrument, a probe, a dental mirror, and a spoon excavator, plus a vacuum with a tip. One brand new mirror top is included. While used, these items are made of durable stainless steel and are still usable. I have two other sets for sale. Please take a look as the tray specifications differ. Dentistry
