Children's inhaler spacer, transparent design for high visibility. - Brand: AeroChamber - Color: Transparent/Green - Use: Inhaler spacer - Target age: Children - Function: Aids in the inhalation of medication - Design: With hand illustration Thank you for looking. This was used when my child with asthma was a toddler and couldn't inhale their medication properly. The inhaler is set in the green part (3rd image), and the child holds the mouthpiece (4th image) to use it. My child has grown older and no longer needs it, so I am selling it.
