These torches are fast, safe and easy to use! We recommend using a torch like this with our custom brand tips. These "kitchen" style torches are safe to use indoors and operate a lot like a large lighter, but probably aren't powerful enough for tips larger than about 3" in diameter. They will work, but the heating time might make a more powerful propane torch more time efficient. The torch is refillable with a standard butane bottle, Butane is sold separately.
