From one side, it looks just like what's shown on the MITB website, black coloured handle and striker. The flint part is about 75mm (3") long, and looks like it's about 8mm in diameter, but when you look on the other side, you can see that it's really just a small 3mm (1/8") diameter magnesium rod glued to an 8mm diameter piece of aluminium. Although the magnesium rod does make sparks, the aluminium side obviously doesn't make any sparks whatsoever. I'm disappointed and feel a little ripped off, because it's not at all like the one shown in the pictures on the MITB web page, which definitely look like solid magnesium.
There are other ones on the MITB website that are much better. I also ordered another one, called "Wilderness Survival Magnesium Fire Starter (Large)" on MITB, product #00879657. It costs €1.50 more, but is a solid magnesium rod. Much better.
So... delivery was good and fast, but the product is not as described. Pity. See my picture of it below, and you'll see what I mean.
MITB saw the review above, and without my even asking, offered me a partial refund, which was enough to order the Black Lanthanum+Cerium+Alloy Flint Stick(25g) (MITB product #00492469). When I receive it, I can keep the handle and striker, and just replace the small magnesium rod with the new one, ending up with what I should've originally received.
I have to say, despite the inconvenience, it really is reassuring to know that MITB will always do their best to ensure their customers are satisfied. Because of that, I've changed my rating to 5 stars. Thanks, MITB!
