Unless the above poster is willing to lock down or show the lantern to provide proof, I would suggest caution folks. No offense, OP but it is pretty standard for folks when the items are large ticket... even without controversy... to ask for proof visually in-game.
That being said, if proof is provided, I would suggest both seller and buyer use a safe third party to conduct the transaction. That is for the safety of both sides.
Now this moderator is going to go have her coffee and take my kids to school... when I come back, I will take another look at the above threads and start handing out spankings for ones I deem to be RoC violations. I would suggest you all edit your posts if you are concerned before I return. You'll have a couple hours, so use them before I come back.
