Shinekoo10 Piece Reusable Butane Nozzle Adapter Convert Cassette Tank Into Inflatable Tank Lighter Spray Gun Universal Gas Refill Head

Item worked perfectly as described. I had no problem using them.

Converts the larger “stove” size butane canisters so you can use them to fill the smaller torches. Works perfectly

This little tool allows you to use relatively inexpensive camp stove butane to fill or refill lighters and torches that use it.It's a little messy when you get started, but once you get the hang of it, things go pretty well.I am not sure why they send a 10 pack. 2 or 3 would be more than sufficient, unless you use a butane torch for a hobby or something.

They work perfectly

Doesn’t fit the different gas refill needles. Useless!

It doesn't work for any of the butane lighter, tried it on a few of mine and none of those take in any.
