Thank you for viewing. This is a Razer BlackWidow TE Chroma V2 US version with yellow switches, an English keyboard. Rest assured, this is a genuine product from a reliable source, brand new and still sealed. (This is the last one I have. Please consider it if you're interested.) To prevent unauthorized use such as third-party product registration, the serial number has been masked. However, you can confirm it when the product arrives. Please note that this product is new and unopened, so I cannot confirm its operation. I apologize, but the transaction will be completed by handing over the package as is. *If you would like to confirm the contents, please ask. If I confirm your intention to purchase, I will open the package and inform you of the results. Also, please note that because of the long package, I don't have a suitable cardboard box. I will basically wrap it in air cap for shipping. You are welcome to purchase without comment, but if you are in a hurry, I recommend confirming my schedule before purchasing. (I may be slow to respond due to work or being out.) If you have any questions or concerns, please feel free to ask in the comments section.
