Premium English Flints - 1/2" Flintlock Ignition Flints - 2 Pack - MZ1206

I've not yet had time to evaluate flints.

So, flints and jaw pads were in my mailbox today.
As promised, I put them to use...the flints were incorrectly sized to my Hawken Woodsman. This gun takes 5/8x3/4 to fully engage the frizzen width; without touching the barrel or bottoming out in the pan.
I received 1/2x5/8 which will create a groove in the frizzen and cannot create spark equal to the above described.
Now, that said; the jaw pads(3) are of a fair quality when referring to compressability and conforming to the various shaping on back of the flint. Which are like fingerprints (no two alike).
I'm not crazy about the smooth side(belt leather) but it seems to hold for now. If your selling flints in pairs...why three pads?
Okay, I compared some Missouri chert, and English flints(two different sources) under magnification.
The MZ1206 had several hairline cracks and a few inclusions as compared to the darker English flints I have, having no hairline cracks, chips but a small inclusion. Density of sedimentary grains seemed relatively the same. Missouri chert is another beast, but it works.
In conclusion, what I received from Muzzleloaders.com is adequate and will give you a bang for your buck(pun intended).
I would rather see more substantial jaw pads(slightly thicker) and not embossed.
Although the flint was undersized, it did produce spark.
IMHO, a deal breaker in terms of "catching the comsumers' eye" would include a few flints and jaw pads included with the purchase...to prime the pump...so to say.
