Inhaler mask for ages 1-5. I haven't used this in a while and have been storing it. This device was a great help, but when I suddenly started asthma treatment, the expense was a bit much at the time. At first, I was scared of direct inhalation, but I gradually became able to inhale without the inhaler, and now I no longer need it. I will sell it at a low price to someone else who needs it. Although the transparency is somewhat diminished due to use, I think it is still usable. When shipping, I will enclose a copy of the instructions from the internet. *I have another one of the same item for sale, so I can ship them together. Thank you for looking.
