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)

I ordered the 3-pack, and all came in good working order, no complaints there! The only problem was my own doing! When opening the bottom to put the lighter fluid in, there's a little spring behind the little screw (see photo). If you lose that spring (as I did, because I wasn't expecting it, and it just flew off into oblivion when I undid the screw) there will be nothing left to apply pressure to the flint, and so it will spin, but no longer make a spark. That tiny little spring will incapacitate the entire device, so be careful. Otherwise the others all work perfectly.

Great little back up lighter. They are very small. All came in excellent condition, work perfectly, and have good seals, no water leaks in and the fluid lasts longer because the vapors cannot escape.

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.

Got as a stocking gift for my husband! I will update the review once he gets to try them out. They are super small and super cute, you can attach it to your car keys what is really cool. Not sure if they work amazing as my husband haven't tried them yet.

Received quickly, which I filled with some standard kerosene, and all 3 worked fine, and have one on every keychain in the house just in case. Fire comes in handy when it's on-hand at all times, and it burns for a solid minute or so. YMMV, and I wouldn't daily drive it unless I had two for when the other ran dry, but it's a perfectly useful tool that adds negligible bulk to my keys, and it comes in a 3-pack.
