I recently bought kiribi flints and

For the longest time I’ve been working on a purchase of a few thousand Flint’s from China. I finally decided to actually invest in some good flints and see if there was a difference and let me tell you the difference is ridiculous. I’m never gonna buy Chinese ones ever again. I don’t know if it’s just that I bought crappy ones or if this brand is just really good.(either or )it’s a game changer for me but I use my lighter a lot. Do you guys have any experience with different Flint manufacturers or types and hardnesses is there somebody here that can talk to us about that please maybe? there’s different hardnesses and stuff right? By the way, the crappy Chinese ones were gold and crappy and these are black and better.

Is it just that I had a crappy crappy flints? How about zippo Flint are they as good as these cause this is night and day for me
