OMRON NE-C28 nebulizer, with accessories (mouthpiece not included), and instruction manual. Purchased new in February 2020. - Brand: OMRON - Model Name: NE-C28 - Accessories: Air tube, inhalation mask (small), nebulizer kit, baffle, inhalation mask (small), inhalation mask adapter, replacement air filter - Manual: Instruction manual included - Includes carrying bag Mouthpiece is the only item missing. Please be aware. Used for several years. Accessories have been replaced during use, so there is no yellowing. There is a white, melted area at the end of the air tube, which is slightly melted due to heat during boiling sterilization. There is no problem with attachment, but if you are concerned, please purchase new accessories. Also, the air connector (the part that connects the hose to the main unit) is slightly bent. This is probably because the air tube was pulled during use. There is no problem with air supply. Thank you for viewing.
