Random Market Board Question

[Kaldarus]

So I was selling off some items that I had recently crafted, and I came across this "flag" on the right of the name of the buyers time stamp when I looked into the history of an item I wanted to sell (I like looking at the history to see if it is worth putting up on the market board now, or saving it for later). Anyone know what this flag means? I tried googling it myself, but came up with no answers as of yet. Thanks in advance.
