Bit Trade One's pantograph gaming keyboard, the bitFerrous BFKB113PBK. I purchased this on Amazon in March 2021. I found it while organizing things at the end of the year, as it had been stored for a long time, so I'm putting it up for sale. I haven't used it continuously, so I'm not sure how long I've used it, but please check the photos for the condition. The box has a small tear. The back of the keyboard still has the original film attached.
