NuPhy Air75 84-Keys Wireless Mechanical Keyboard retail

Product Name: NuPhy Air75 84-Keys Wireless Mechanical Keyboard retail
I am selling this NuPhy Air75 84-Keys Wireless Mechanical retail Keyboard with brown switches. (I removed two keycaps in the last photo to show the brown switches.) This keyboard can connect wirelessly via Bluetooth or the included 2.4 GHz USB receiver, or it can have a wired connection using the included USB-C cable. It comes as shown. It comes with a USB-C cable; a 2.4 GHz USB receiver; a keycap/switch puller; 4 extra stick-on feet for the bottom of the keyboard; 2 magnetic feet; 3 extra keycaps; 3 extra switches (one blue, one red, and one brown); stickers; and a quick guide. The box had been opened when I purchased it. I only tested it briefly and never actively used it. The box has wear, tears, and some cuts.
