Features: Simplified 87 key configuration, reducing keyboard size while retaining complete keyboard functionality, balancing aesthetics and practicality. The GASKET structure provides moderate soft elasticity, while the PC placement board and single key circuit board opening optimize rebound and stability, resulting in a cleaner sound. The sandwich cotton combination + IXPE shaft bottom plate + PET sound-absorbing pad + shaft base sound-absorbing foam + silicone filling at the bottom effectively fills the keyboard's internal cavity, reduces cavity sound, and better restores button sound. All key positions can be replaced with switch bodies, compatible with most three-pin/five-pin switches on the market. Users can freely change their preferred switch bodies to better experience different tactile sensations and button sounds.
