The Batman branding iron "is not a toy! You can do some serious damage to people and property with this hot item if you aren't careful! By purchasing this item you are agreeing to not hold us accountable for anything dumb you do with it!"
Those words of warning and CYA statement come straight from niquegeek, the Etsy shop that makes these Dark Knight symbol-searing irons that snap onto a standard Bic lighter. However, I would like to echo them myself. Kids, a Bat-Signal that gets hot enough to burn itself into your flesh is not a toy! More importantly, if you choose to treat it as such and do something dumb with it, it's not my fault, problem, or responsibility to deal with. That goes for my nephew Kyle too. Even when I'm babysitting you.
The Batman branding iron sears everyone's favorite nocturnal icon into fun places such as notebooks, headboards, and Mom's antique Wellington chest. To use, affix the 3D printed piece of steel onto your lighter, flick it on, and hold the flame on the metal end for 60 to 90 seconds. niquegeek recommends honing your branding technique by practicing a few rounds on a piece of scrap wood.
