Used a few times, then stopped using it, so I'm putting it up for sale. Blue soundproof earmuffs, foldable for compact storage, and come with a bag, so you can hang them on a hook on your desk and have them ready to use anytime. - Instruction manual: Included - Color: Blue - Design: Foldable I'm also selling other types of earmuffs, so please take a look at those as well. ※This product is also listed on other sites. I will remove it as soon as it sells, but if there is a booking conflict, I will prioritize the first person to purchase and may have to ask for a cancellation. In that case, I apologize for the inconvenience. #KidsSoundproofEarmuffs #AuditorySensitivity
