I am selling this item because I have had fewer opportunities to use it. I purchased this keyboard new for work, and I am now putting it up for sale. All original accessories (box, manual, etc.) that came with the keyboard are included. I have confirmed that it is in working order. The "Ctrl" print on the left Ctrl key is slightly faded. Please refrain from purchasing if this is a concern. This is a tenkeyless (TKL) keyboard. The APC function allows you to individually set the actuation point for each key. You can set frequently used keys to a shallow actuation point and less frequently used keys to a deeper one, preventing typing errors while maintaining comfort. I am also selling a separately purchased Archiss keyboard case (see image 5). It fits perfectly, and the inside is made of a brushed material for protection. *Please contact me if you do not need the case. ---------------------------------------------------------------------------------------------------- 【R3S Keyboard】 The R3S keyboard, an upgraded model of the R2 keyboard, is newly released from REALFORCE, which is popular for its unique typing feel using the electrostatic capacitive non-contact method! 【Silent】 The typing sound has been silenced while maintaining the same typing feel. You can use it comfortably in the office or at home. 【APC Function】 The key actuation point can be adjusted in 4 stages: 0.8, 1.5, 2.2, and 3mm. It can be set to suit various situations. 【Software】 You can use even more features, such as the keymap swapping function, with the dedicated software. ---------------------------------------------------------------------------------------------------- Search Keywords REALFORCE R3S Keyboard 30g English Layout Black R3SD13 Topre Top-of-the-line Keyboard Wired Connection US Layout HHKB
