● Usage Period: Used daily for about six months, then stored in a dark place. ● Condition: I replaced the keycaps with different ones soon after starting to use it, so I think there's not much feeling of use. The USB connection is TYPE-C on the keyboard side and TYPE-A on the PC side (see photo 5). I added photos of the keyboard lighting up. There's a mode where all the keys light up (photo 6), a mode where only the pressed keys light up (photo 7), and a mode where the light flows horizontally (photo 8). There are also various other modes, such as light flowing diagonally and rotating. The LED colors of the keys only light up in the colors shown in photo 6 (for example, the "Q" key only lights up green and not other colors). By the way, I always used it turned off, so it was the first time I saw it, but the way the light flowed was quite enjoyable. ● Other Notes: We inspect the item, but please forgive any oversights.
