Razer BlackWidow V4 75% Japanese Layout

Razer BlackWidow V4 75% JP keyboard, black.
Purchased around June 2024, used for about a year and a half.
Includes one USB cable. No outer box or instruction manual.

It's currently working normally without any chattering issues, but please be aware that such issues can occur.
I cannot respond to claims like "the keyboard is slow to respond" after purchase. I do not accept returns, so please purchase only if you understand that this is a used item and are prepared to, for example, buy replacement keycaps to address any potential issues.
