Zippo 打火石

The flints fit perfectly into my lighter and produce a strong spark every time. It’s nice knowing I have six replacements on hand for when the current one wears out.

Picked up a pack for my old lighter and was pleasantly surprised by how consistent the spark is compared to the generic ones I'd tried before. Each flint strikes reliably for weeks with normal use.

Finally, a pack that actually has more than two flints that work on the first strike. These are noticeably more sparky than the off-brand ones I tried before.
