Thank you for viewing. This is a Gigastone Gaming Mouse 3200 DPI. I bought this because I wanted the keyboard that was sold as a set, but I already had a mouse, so this one has only been tested for functionality and is practically unused. I looked it up, and it seems to be sold for ¥2990 on Amazon if you buy it separately. The cord is also soft and easy to handle, and the response seems to be almost the same as the ¥15000 mouse I'm currently using. I think the performance is good for the price. Gigastone Gaming Mouse 3200 DPI, wired gaming mouse, adjustable RGB backlight, 8 programmable buttons, 256KB onboard memory It will be shipped without the box. Instant purchase without comments is OK. Thank you.
