Single Edge MAX 黑標刀片（補充包）

I was skeptical about the blade being twice as thick, but it glides through my shave with zero tugging. Eight blades per refill lasts me ages, and the quality from Seki City really shows in the smoothness.

Three months on one refill and the blades still slice through my morning shave like it’s day one. The thickness of the steel is no joke—you can feel it holding an edge longer than anything I’ve used before.

Eight blades per refill and they've lasted me a full quarter, which is exactly what the description promised. The extra thickness is noticeable on the first pass—no flexing or tugging like standard blades. I'm already on my second pack and haven't had a single dud yet.
