Vintage ergo keyboard. One of the first model on market with a split design. This is an early edition made by Mitsumi (later models, with different model numbers, are made by Silitek and others). Key switches use KFK Type technology, which uses individual rubber domes over membrane PCB. KFK is said to have a force curve similar to Topre switches, used in the Realforce series of boards (according to Deskthority). This is the only ergonomic keyboard that uses this type of switches.

Split designs are good for reducing pronation and keeping wrist straights while typing. This can be very beneficial for those suffering from RSI / carpel tunnel syndrome, and help reduce typing related pain and fatigue. Note that the seller is not a healthcare professional and this is not medical advise. Buyers please do own research.

This keyboard has been fully dis-assembled and every individual dome and keycap cleaned. It is in near mint cosmetic condition and perfect working condition. All key switches tested working after clearning. No key press chatter (and never will, given the technology).
