I purchased this a while ago and have used it a few times. The main unit has been disinfected. I'm selling it because I found it while cleaning. I'm willing to negotiate a small discount, as it's better than throwing it away. <Contents> Main unit, tubing, mouthpiece (1), instruction manual I will pack the main unit and cushioning material in the box shown in the first image, and then place it in a waterproof bag before shipping.
