Excellent Condition Thomson Elite X4 stem, 0 degree, 100mm, 1 1/8 steerer.  I had this on my Yeti a couple of years ago after I built it up but only for about 2 months before I figured out it was too long.  I switched to a 90, which is why the bag for this one says 90mm.  The stem for auction is 100mm.  I'm including the bag from my replacement stem.  This one has been siting on the shelf since then. No scratches, great shape.  One of the steerer bolts looks a bit rounded out but I was able to get an allen key in there.  I think you'll be OK but nothing you LBS likely has in stock.
