The Firefox Refillable Mini Butane Torch produces an intense blue flame and is useful for anytime you need to apply heat precisely. Powered by butane, it is a very handy tool that can be used for soldering, gunsmithing, arts and crafts and more. Just a push of the button triggers the piezo-electric igniter to produce 2500 degree flame. Lightweight and portable, the Firefox is refillable with readily available canned butane.
