This is a set of 2 replacement nozzles for the PHILIPS AirFloss Ultra (HX8032/02). I purchased these on Amazon and have stored them at home for a long time. Although unused, I am listing them as "Like New" because I peeled off the top of the box. *I only peeled off about half the thickness of the paper, and the product has not been opened. <Attention> These nozzles cannot be used with AirFloss models that do not have a metal ring on the nozzle attachment part.
