don't price this in keys if you're pricing it this high

Screenshot it from your inventory area, next to trade offer there will be view inventory history, click that and screenshot, make sure you shiw the effects

It only leads to your profile, you need to screenshot it because trade history is private and only viewable by yourself only.

there should be a key on your keyboard that says print screen or something along those lines. if you press it, it will take a screen shot. go into paint and press ctrl- V and you can paste the screenshot into paint. then you can crop out anything unnecessary (but be sure to display the full trade and make sure everyone can tell its the full trade) then save it and upload it to an image sharing website like imgur.

screenshot it. Press the "print screen" button when you're over the trade, and you can save it in MS Paint. Then upload the image to imgur or some bucket site like that and link to the picture
