【Perfect Fit Design & 3-in-1 Magnetic Functionality】 Designed with 1:1 precision measurement of the Surface Pro 3/4/5/6/7 body shape, integrating "magnetic adsorption connection, 15° ergonomic tilt, and body protection." Switch instantly between tablet and laptop with one touch, and the strong magnetic adsorption completely suppresses wobbling. The 15° tilt during typing reduces arm fatigue by approximately 40% (compared to flat types), and when not in use, it covers the entire body to protect it from scratches and dust, making it ideal for business trips. 【Touchpad & Numeric Keypad Integration｜Optimal for Spreadsheets】 Adopting the rare "touchpad + numeric keypad integrated design" in the Japanese industry! Simply press the Fn+Space key to switch between "touchpad mode" (cursor movement, zoom, etc., standard Windows operations) and "numeric keypad mode" (direct input of numbers and arithmetic symbols). No need for a mouse or separate numeric keypad during accounting work or Excel spreadsheet calculations, maximizing work efficiency. 【Bluetooth 5.0 & Seamless Switching with Dual Device Connection】 Achieves stable communication up to 10m with the latest Bluetooth 5.0. Register two devices with Fn+Q/W and switch with one touch. Smoothly compatible with Windows PCs (Android and iOS smartphones can also be connected) and tablets. (Please note that there may be some keys that do not respond due to incomplete compatibility with smartphones.) 【Japanese Standard JIS Layout & Silent Design for Focused Work Anywhere】 Adopts the Japanese standard JIS layout optimized for Japanese input. With silent keys, you can concentrate without worrying about your surroundings during meetings or in shared offices, and the key rebound force is moderate, making it less tiring for long hours of input. 【7-Color Backlight & 3-Step Dimming for Easy Use in the Dark】 Supports 7-color backlights: red, green, blue, white, purple, cyan, and yellow, with adjustable brightness in 3 steps: [weak → medium → strong → off]. You can instantly grasp the key positions even in dark places such as nighttime remote work or in-flight work.
