The World's Smallest Kerosene Lighter! Height 2.5cm/ 1.3cm Capsule Lighter Portable Metal Miniature EDC Gear Waterproof Tiny Peanut Lighter (Fuel not Included) (Mini 3 Pack)

Almost too small for someone with fat fingers. But if you want a keychain small and lightweight lighter this is it. It appears to be well made. I only wish it came with an extra O-ring or there was a way to buy another one. It holds a surprising amount of regular zippo lighter fluid. As small as it is it's a bit tricky to handle but I managed to do so without getting burned. Along with the mini-flashlight, the compass and the pocket knife (all purchased on Amazon) it's a pretty well rounded EDC kit that I can completely enclose with my fist.

I love these things. They appear well constructed. They look better in person compared to the picture. They all work great. I've left them sitting in different places for weeks on end and they haven't dried out. I hate to say that you might need to be careful about cross threading. One product was a little iffy.

This is too cute. My boyfriend loved it. Looks even smaller in his big hands

Great lighter! Light, sturdy, reliable. Poor quality ring. I carry my lighter on the key chain. Lost one, and nearly lost another, because of the ring easily gets unwound by accidental pulling.

Seem to be good little lighter. Fluid doesn't seem to evaporate when not in use. I carry them on a key chain.

Smaller than expected. Also uses butane. Sealed with an O-ring so it won’t leak.

So, this little lighter works pretty darn good. I am using coleman white gas to fill it. Takes just a few drops. The way to do it is to open the lighter, remove the bottom felt and then drop in some white gas to fill it. It maybe takes 10 drops total before the cotton is saturated. Then, put it all back together. For ultralight backpacking, this has worked great for me. I need to refill it before every trip, but it has worked for me without issue. I have tested it, it will burn for me for about 2 1/2 minutes straight, however this is not a good metric of how long it will keep a flame. Because in the long burn test, it gets so hot that fuel comes out of the wick faster and the flame gets very large. Plus, when I did this I burned the wick a bit and I had to trim it down a bit. But during regular use, where it's lit and a flame burns for maybe 10-20 seconds, it'll do this several times. I use this little lighter to light mosquito coils to keep the bugs off me. Don't overtighten the cap. It has yet to leak a drop of fuel in my backpack. I highly recommend!

I wanted this as a gift for a friend for his birthday, it arrived the day of, but unfortunately it’s a broken product. Overall not a good purchase; it was slightly used upon arrival and the wick was burn out black and short. Not even a spark is possible just a faulty fake product. Added kerosene for fuel, which was easy, but still no spark or flame. No spare parts in the bag, no instructions. Doesn’t function well, leaks everywhere. Very very disappointed I would not recommend this lighter to anyone.
