Thank you for considering this product. This is the Logicool G G512r-LN gaming keyboard. *Gemswit's sound dampening & key stroke adjustment O-rings (clear) are installed for quietness. I am selling this because I have purchased and am using a different keyboard now. It was working perfectly fine until just before I switched to the new one. Both the keyboard and the O-rings were purchased from Amazon. Please note that this is not a pure Logicool G G512r-LN gaming keyboard, as the O-rings are installed. You can use it as a pure Logicool G G512r-LN gaming keyboard by removing the O-rings yourself after receiving it. As shown in photos 2 and 4, there is some paint peeling. I couldn't find any other noticeable scratches or stains, but there is a sense of use, so please understand that this is a used item and is managed by an individual. It will be shipped via anonymous Rakuraku Mercari delivery.
