I'm selling this because I used to use it but don't anymore. It's a keyboard and mouse that can also be used as a converter for the Switch. It feels good to use and can also be used as a regular keyboard. Please consider purchasing it! This is a GameSir gaming keyboard and mouse set, equipped with programmable keys to support comfortable gameplay. - Brand: GameSir - Set Contents: Keyboard, Mouse, USB Adapter - Connection Type: Wired - Keyboard Type: Gaming Keyboard - Features: Programmable Keys Thank you for viewing.
