Sanwa Supply Wired Compact Keyboard with Numeric USB 103 Japanese USB to Adapter Black Keypad, Connection, Keys, Membrane, PS/2 Included,

Despite its compact size of less than 400mm wide, it is a full keyboard with a numeric keypad. The key pitch is 19mm, the same as a standard keyboard. We use laser printing, which ensures the characters are highly durable. When not in use, the keyboard can be stored upright. The keytops are membrane type with a standard deep feel. It comes with a USB-PS/2 connector, so it can be used with either a USB or PS/2 connection. The frequently used "ENTER" key has been enlarged. The cable has a groove for fixing the cable, which makes it easy to manage. (It can be fixed in three directions: left, right, and center.)
