Most likely lent it to Jackler to see if he could broker it, because it ends up back in his inventory

Sold with a Purple Energy Wraith Wrap (outdated at 116) for a Phosphorous Pencil Pusher (unpriced)

http://backpack.tf/profiles/76561198131966769#!/compare/1469923200/1470009600

I couldn't get valid proof for the Wraith Wrap or the Pencil Pusher, so this can't be used

That's all the sales as far as I can tell.

Tried to use this to help price the Phosphorus Pencil Pusher, but that pencil has at least one thing in every sale to make it invalid. So sad.

Feel free to prove me wrong, gather support evidence, give me advice, break a lamp, blame me for it, or let me know if any others have sold.
