AVANTEK HIGH FIDELITY EARPLUGS These are AVANTEK high-performance earplugs. Available in sizes L, M, and S, and come with a Japanese instruction manual (with usage instructions). They also come with a sturdy metal case, making them convenient to carry. Although they have not been used, they have been taken out of the box and bag a few times for product inspection. Also, due to long-term storage, there is some damage to the plastic bag, outer box, and instruction manual. Please refer to the photos for the condition. We would appreciate it if those who understand the storage conditions of a private seller would consider purchasing. If you have any questions, please feel free to leave a comment. Thank you.
