ELECOM Wireless with Numeric Keypad and Silent Mouse Slim and Compatible with and Keyboard, 2.4GHz, Quiet, 5-Button Set, Compact, Windows, ChromeOS,

This wireless, quiet, thin keyboard is designed to be truly quiet, yet provides a light typing feel. Its compact size allows for efficient use of desk space, and it includes a numeric keypad for convenient number entry. The silicone rubber attached to each keycap reduces keystroke noise by more than 90% compared to conventional products, making it ideal for use in places and times when noise is a concern, such as public facilities, conference rooms, late at night, or early in the morning. *This is the result of comparing the sound energy calculated from the sound pressure level of the keystroke sound between this product (approximately 15 dB) and the previous model TK-FCM062BK (approximately 45 dB). Sound energy is a value calculated from the measured sound pressure level (bell value) and the reference value (the minimum sound level that humans can hear). Equipped with its own firmware, it can be used on Windows, ChromeOS, and macOS. It uses thin keys with a keystroke of 1.4mm, allowing for quick key input.
