Thank you for viewing this product. Used, Excellent Condition Topre REALFORCE 91 USB-S Keyboard This is a classic PC keyboard made by Topre, which is now discontinued. There are no issues with its operation. I liked the responsiveness unique to wired connections and the peace of mind that comes with no chattering. I used it for work for about 2 years after purchasing it new, and then stored it as a backup. We appreciate your understanding if you are purchasing a used item. The exterior has been cleaned with an air duster and alcohol. Includes the original box and instruction manual. * Please note that the original box has stains and traces of shipping labels. ■ Product Description --- (Excerpt from the official website) --- https://www.realforce.co.jp/products/discontinued/91UBK-S_NG01B0/ ・Achieves the ultimate key touch with electrostatic capacitive non-contact switches The ultimate key touch and non-contact structure that prevents chattering, chosen by professional key punchers in data centers, etc., and the step-sculpture structure that reduces the burden on fingers and smooths finger movement, allowing for comfortable operation even during long hours of key input. ・Ergonomic step sculpture The step-sculpture structure with steps in each row fits the movement of your fingers, making it easy to input keys and comfortable for long hours of operation. ・High durability It has passed a key input durability test of 30 million times. --- Connection type...Wired Keyboard layout...Japanese Key switch...Electrostatic capacitive non-contact method
