I have this showing in my inventory. Don't know what it is but I think its a bug? Oh a trade recently canceled and one of my other friends mentioned the same thing happening so perhaps it was from a trade ending? I think the two items in question are and but they are still appearing in trades so not sure what to do

I have this too. I had a trade that finally cancelled after, I think 2 months? and some of the trade items are in inventory along with non tradeable items.
