Specification Material: zinc alloy Size: 8 x 3.8 x 2 cm Weight: 105 grams Package List 1* Triple Jet lighter (without gas) 1 x VVAY Gift Box Adjustable Flame regulator is located under the bottom of the lighter (the ring around the filling hole and NOT the small screw), follow the “+” and “-” sign to rotate it. The flame height must be adjusted again to the desired level, since the butane pressure in the fuel tank decreases after a period of operation. How to refill: 1. Set flame regulator near (-) position. 2. Release the remaining gas before refilling (use a small screwdriver to slightly press the filling hole to release the gas). 3. Turn the lighter upside down, first shake the gas cylinder and press it for 2-3 seconds for 3-4 times (choose a gas can with a long nozzle). 4. Shake the lighter several times after filling and adjust the flame before first. Note Lighter is shipped WITHOUT butane due to DOT and USPS Safety Regulations, please fill with butane fuel before use. The lighter will not ignite at the lowest setting because there is no butane pressure. Keep away from children, face, body or flammable things. Warranty Lifetime warranty provided for this lighter, full refund or free new replacement if broken.
