Safe and comfortable baby earmuffs, adjustable and lightweight. Soundproof earmuffs 3 months - - Brand: MUMBA - Color: Blue - Features: Adjustable, Lightweight, Zero Pressing - Target age: Baby/Toddler Thank you for viewing. I purchased these online, but I accidentally ordered two of the same item, so I am selling the unused one. I opened the box and disposed of it, so I will wrap it in a plastic bag and ship it in a cardboard box, etc.
