A startling trick- with a bonus! A small pocket knife seems to suddenly change from black to white and back again at your command. It can even change to black on one side and white on the other side!
These knives are known as Enardoe knives. They are an easy-to-handle thin design with a BONUS feature not found in any other color changing knife set.
Bonus #1:- this Enardoe knife is ALSO an "open- no open" knife. It only opens if you know the secret! You can open it, but no one else can. Back on the market after 20 years, and at a great price!
Bonus #2:- this comes complete with a whole routine you can use!
