Sublimation Lighter and Bottle Opener
The Sublimation Lighter is a gas filled lighter. However, for safety reasons these are sent from us gas free. It has an electronic spark flint to light the flame. It is operated by twisting the front dial clockwise. This front dial also has a printable circular piece of metal. Finally, when printed this insert is affixed to the dial with superglue or similar (not supplied).
The Lighter also provides the added function of a bottle opener. This could certainly be used as a means of fixing to a key ring if one was that way inclined.
