Ring-shaped earplugs, adjustable size, and come with a storage case. I bought these on Amazon for my child to attend a live concert, but they weren't needed, so I'm selling them. (These are not for soundproofing, but earplugs to protect ears from noise.) Wiped with alcohol and are almost new, but please understand that they are used items before purchasing. - Brand: loop - Size: XS, S, M, L - Manual: Experience 2 - Design: Ring-shaped earplugs - Case: With storage case Thank you for looking.
