One of many items that may come to mind when thinking about an old, creepy, abandoned house is a skeleton key!
This skeleton key keychain is made to resemble old antique keys but it also has another function - it works as a bottle opener! The key measures about 3.1" long and about 1.1" wide - not counting the matching 1" bronze toned hinge ring.
A beautifully haunting, functional piece to dress up your set of keys!
