Hmm - I looked at one of my Thorins and it looks like while the fur was attached to the main part of the coat w. stitches, in back they folded the "fur" and trimmed and used fabric glue to shape the fur in back, so it would fold and lay flat. E.g. this is fine, as sometimes adding stitching to thick fabrics just causes a bulky seam or bump. So yes, in certain sections like over the shoulders and other places, there is no stitching.
The folding, trimming, and gluing is probably where those extra fibers came from. If your Thorin look like other various pictures, it's probably OK. Re your pics, to me that is what the back is supposed to look like, kind've w 2 folds of fur that were shaped and designed to lay flat against the back. (So Orcrist and the scabbard belt will lay nicely across the back).
One think ASMUS excels at, is 1/6 scale costuming.
Re the sword Deathless, yeah, on one of mine it's a tight fit. Hold the sheathe carefully - so you don't rip off belt. Warm up sheathe with blow dryer if you can.
Then wriggle the sword back and forth -
it'll be tight - but with some warmth and persuasion the sword will go in, all the way. U can try gently pushing at the top of the sword, while holding the sheathe (like put Thorin down on a desk or someplace so you are not straining the straps, put a blow dryer on the sheathe for a bit, and push the sword in.)
Let us know how it goes! This stuff can be nerve-wracking for sure, and sometimes stuff does break, but most stuff can be fixed easily, and at times better than the original. ASMUS tho I think has done a good job with its costumes.
Yes - really sorry that happened to you
. I would remind the seller of that, too. Already one huge mistake so they should fix or send replacement as soon as possible, rush order
. I'd be pretty upset! It's sad because this really is a great figure.
