This is an external NVMe SSD case from CENTURY. * https://www.amazon.co.jp/dp/B08CZJWNRC I purchased it around July 2021 for 4500 yen. It still works, and it inexplicably glows a lot. I used it for formatting NVMe SSDs, but I'm selling it because I bought a different one. The included accessories are as follows: * Main unit * USB A-C cable * USB C-C cable * Heat sink? * Screws and screwdriver * Instruction manual * Outer box
