I am selling this keyboard because I decided to use a different one, even though I purchased it here. I've used it only a couple of times to test it out. It has a low profile, making it easy to type on, and it's light, so it seems suitable for carrying around. Connection type... Wired/Wireless (Bluetooth) Key switch... Mechanical Keyboard layout... English The following is quoted from the previous seller: --- I have hardly used it. All accessories are included. - US layout, Brown switches - RGB backlight - Low profile Gateron mechanical - Hot-swappable I purchased it through official channels, so it is, of course, technically compliant. Although it is almost unused, it is still a used item, so please confirm before purchasing.
