2 systemx e blades. Missing boards and eyes. Brand new inbox

[woouulf]

So I've had these two system x e blades laying around for a few years. Figure I'll never get around to getting boards and eyes into them. These are brand new in the box. And yes they are two of the exact same. Both are missing the boards and eyes. I had planned to just drop in a couple of e-blade boards and eyes but never did get around it. Take the pair for 500 plus shipping.
