Don't try to break open car windows or defeat aliens from alternate dimensions with this Thor Ragnarok Keychain - unfortunately, there is no substitute for the real Hammer of Thor. This silver-tone hammer-shaped keychain, engraved with the Marvel logo and accented with a lightning bolt-shaped charm, will, however, always make your keys come back to you when you call for it, just like the real Hammer. Wait. No. Sorry, wishful thinking.
