A disposable fuel can for a lighter has been developed. The disposable fuel can includes a lid, with a depressible valve, connected to an opening of a fuel storage area and an integrally formed elongated cylindrical body forming the fuel storage area. The elongated cylindrical body has a diameter of between 15 and 25 millimeters, and a length of between 35 and 75 millimeters. A longest length of the disposable fuel can is less than 95 millimeters allowing the disposable fuel can to be inserted into the lighter.
