The windproof, oil filling, and movement can be used separately. They can be used in campfires and candles for more than 45 minutes. They are particularly suitable for outdoor sports use, especially in high altitude areas above 4500 meters above sea level. With strong visual impact, manufacturers used bullet shells as raw materials after World War I and received unexpected results. Until now, they have followed the traditional design style and retro style. With the lid open, it is possible to ignite without touching the spark wheel by hand. This is the IMCO process concept. IMCO flint wheel structure is delicate, similar to the shape of the blade so that each time enough sparks are generated, using the lever principle, there is a wrench to help without direct contact with the steamer to ensure the rotation of the flint and eliminate the uncertainty of sliding friction. In addition, sealing the lid to the friction of the moment to play the role of fuel absorption, IMCO rely on this point enough to make any lighter shame. The ignition of an instant ignition IMCO lighter is unique, unique, and subtle. This is a pipe lighter--it has a removable "fuel tank" with which you can light a pipe (or campfire--anything that requires "distance" from your hand and the ability to tip the flame like a candle). It is windproof, as long as you have the "chimney slide" type thing choked up and the wick trimmed. It is remarkably fuel-efficient, due to its unique fuel tank cap and built-in snuffer that seals around the top of the tank when closed. It is lightweight. I think it's either made of steel or tin, but whatever it is, it's light. It is easily maintained--all you ever have to do is replace the flints (and wicks, periodically. It accepts Zippo brand wicks in a pinch). Replacing the flints is much easier than it is on a Zippo; all you have to do is press on the release catch on the bottom and swing out the innards, which remain in one piece (no stupid tiny little screws to lose).
