Portable Megaphone Hands-Free Headset Microphone Speaker

This is a portable megaphone ☆
I bought this because I couldn't find the one I used for work, but then I found it, so I never used it at all.
I use the same one, and it's very easy to use!
The box is not included. I don't know if the instruction manual was included or not, but I don't remember reading it, so the operation is simple. It has never been used and is a brand new, unused item ☆

Retail price: 2088 yen
