Nikken NIKEN High-Sensitivity In-Ear Hearing Amplifier NK-04

Purchased for my elderly mother, but it didn't suit her, so I'm selling it.
It has only been worn once for testing, so it is practically unused.
For peace of mind, it has been lightly cleaned and repackaged.

For reference, the new price is 9,910 yen (as of January 1, 2025).
