Once you light this, you cant put it out.
This is a metal ribbon of magnesium. It "burns" very hot and very bright. Just a heads up.

So bright.
Wow it’s brilliant when you light it.

Magnesium ribbon
Its magnesium alright, but not pure magnesium. It works to ignite thermite and is a decent fire starter.

Definitely Magnesium Ribbon.
Definitely High Quality Magnesium Ribbon. A little thicker than most. So if you are having problems igniting it, keep in mind that you are attempting to ignite METAL. So it's not just going to flare up with a flick of your Bic. You can probably get it lit with your lighter or matches ( note the plural "Matches"), but it's going to take a while. If you are doing demonstrations or are outside with any wind, I highly suggest using a propane torch. Caught right on in under 3 seconds with my propane torch. No torch? Buy one they're handy. My second suggestion for an igniter is to use firework sparklers, preferably gold colored ( the hottest burning). And be careful! Magnesium burns at about 4000 ( Four Thousand) degrees Fahrenheit, 2200 Celsius. Do not extinguish with water or CO2, it does even worse things. Smothering with sand is the standard procedure and that's just to keep the fire from spreading.

Good budget buy maybe
It's ok but it doesn't burn very hot or long and it's various length strips. Not only long piece. I took about a foot worth lit it between two thin thin pieces of wood and didn't even get hot enough to start the wood on fire

As described. Works.
As described. Value. Works for my experiments.

The "roll" was several smaller lengths, but Mg nonetheless
Picked this up for an element collection I've started. The magnesium is actually magnesium (shocker) and does burn with a bright flame. A quick tip to light it more easily is to cut it with (junk) scissors so that there is a narrow point at one end. This makes for a smaller thermal mass to heat up and you can reliably light a strip with a Bic lighter. Something folks should be aware of is that the "roll" is not a continuous roll but rather a collection of strips around a foot long. I doubt this will be a problem for most folks doing amateur chemistry demos (like burning strips), but something to be aware of if you are expecting longer lengths.

Great for what it was needed for
Works good for what it is needed for. Kept it in a zip bag to keep it dry and safe for next time. Delivery was good and it was it was in one peice.

Burns Great - Please Read
Lots of reviews & some videos of people unhappy with how this lights. This isn't a dynamite fuse, its fairly thick metal so it doesn't light up like a piece of paper. Put the flame on the very tip of the strip & leave it there for at least 5 or 6 seconds. I'm sure there are simple treatments to clean up the magnesium & take the patina off but so far I haven't needed to do this.
