Operation unconfirmed Neo Geo CD controller pad

Received from my senior.
Operation has not been confirmed as the main unit is missing. Thank you for your understanding.
This is an official Neo Geo CD controller pad.

The controller is in good condition with little signs of use, I believe it's quite clean.

Immediate purchase is welcome.
Please refrain from price negotiations.
We will not respond to comments regarding price negotiations, so please be aware of this.

The item will be wrapped in bubble wrap and shipped via Yu-Packet Post.
Thank you very much.
