Mechanical membrane gaming keypad with RGB backlighting. Thank you for viewing. It has 32 assignable keys, a wheel, and a reel on the left side. It's mechanical and membrane, allowing for soft, stress-free typing, and I've been using it with affection. The keyboard has 16.8 million color lighting options. After a few months of use, I'm selling it at a bargain price because I'm replacing it with a new one. The retail price was around 12,000 yen. - Model: TARTARUS V2 - Type: Mechanical membrane gaming keypad - Connection: Wired - Features: RGB Backlight - Number of buttons: 16 - Manufacturer: RAZER
