The Duality is a high-quality butane torch lighter. It has a pocket-proof ignition and a single or double flame to choose from depending on your preference. It also features a large tank window that allows you to keep an eye on the fuel level, as well as making it easy to refill it without issue. The flame can be adjusted with the dial at the bottom and the flint ignition can be replaced if it gets worn out.
It ships empty so you need to add butane gas to it before you can use it.
