OMRON NE-U100 nebulizer, compact and user-friendly design. - Brand: OMRON - Model: NE-U100 - Accessories: Instruction manual, mask, tube, power cord, batteries - Power supply: AC100V 12W - Waterproof rating: IP52 - Country of manufacture: Japan Thank you for viewing. I purchased this thinking my son had asthma, but it turned out not to be the case, so I am selling it. One mesh cap and the mouthpiece are unused, and the mask has changed shape but can be used without any problems. Operation has been confirmed. Used only about 4 times. I am also listing this on other sites, so please leave a comment if you are interested. Thank you. If you need it immediately, I will also include batteries.
