No, they’re not official, but they are neat little items, even if they do appear to be knock-offs. eBay seller shashentao has posted an auction for what appear to be vac-metallized “chrome” Storm Shadow figures in silver and gold. These are not official items, but they are a pretty neat eye-catcher for anyone’s collection.
They appear to be fully poseable, though, being knock offs, there are always some questions about durability.
