The listing, Crown Keychain has ended.
As this item is tightly wound in the box, I'm loathe to remove it. It measures just over 3" long, with the crown measuring about 1" X 1". The keychain feels lightweight so my guess for its material would be plastic. There is a bit of "bling" on this item as noted by 4 crystals(or similar)on the crown. Picture #2 is to show that the back is plain. As this item has remained in this box, it has never been used. Thanks for looking.
