Attack Shark X820 Ultra - 75% Tri-Mode Gasket Wireless Mechanical Gaming Keyboard

The ATTACK SHARK X820 Ultra 75% Tri-Mode Gasket Mechanical Keyboard is a compact, feature-rich keyboard built for clean setups, smooth typing, and flexible multi-device use. Its 75% ANSI layout keeps dedicated arrow keys and essential controls while staying space-efficient for gaming desks, productivity setups, and travel-friendly workstations.
