Travel earplugs with pressure control function, transparent design, and easy to use. I bought these for my child to use on airplanes and used them for a few minutes. My child was able to fly without ear pain, so I don't think we will be using them in the future, so I am putting them up for sale. - Brand: SILENCIA - Model: FLIGHT Air S size, regular size - Quantity: Set of 2 - Features: Pressure control function - Color: Transparent - Purpose: Travel earplugs Thank you for looking.
