Filament Fell Out
I opened it and closed it a few times to test the feel of it as soon as it arrived.  I later went to use it again and the filament was missing.  I later found the filament on the floor.  It must have slipped out of the handle and fell out through the hole in the cover.  I lost the small bright red filament before I could take the photos.  If I did not lose it, I probably could have repaired it.  Cute and solid otherwise so I gave it 3 stars for the design, despite the poor quality control.  Takes a moment to steady your hand to aim the filament back in the sheath.  I bought the Geekidoc version of this at the same time.  It has almost the same design, but it had different quality control problems.  See that review.
