Fully Stock.
All Accessories included. 
Used ~2-3 Weeks.
Disassembled, cleaned and dusted before shipping. 

Functionality:

Great. All keys working as expected. RGB and VIA connectivity are also working. 
Stabilizers are slightly rattly - which is typical for these models.   

Condition:

Great. Only one or two minor scratches on the outer frame - only noticeable if you know exactly where to look. The rest of the aluminum finish is clean and smooth. 
Spacebar has some discoloration on it which is picked up in certain lightings. Doesn't bother me but it may bother those who are OCD about keycap uniformity. All other keys are in perfect condition. 
Pictures of the keyboard disassembled depict scuffing on the top plate. Not noticeable when keycaps are assembled but it is worth noting for those who may tinker with this board.  

Despite these flaws, the keyboard is a real treat to type on. 

History:

Bought this keyboard second hand from someone who only used the keyboard for a couple hours. Gave this keyboard a solid few weeks of use before moving on. Swapped out the switches on this board a few times during its use. 
Did my best to keep this keyboard in excellent condition. The keyboard has been disassembled once to remove prints and oils from the frame and other dust particles.
