Sharpie 大號永久馬克筆 黑色

This marker lays down ink so thick and dark it practically paints the surface, which is exactly what I needed for labeling metal shelving. The tip is huge and durable, making quick work of writing on rough concrete blocks without skipping.

I needed a marker that would actually show up on raw concrete blocks, and this one lays down a dense, opaque black line that doesn't fade. The tip is huge and holds up well even when I'm marking on coarse stone.

I've been using this marker on various metal surfaces in my workshop, and the thick, durable tip lays down a solid black line that doesn't skip. It even works on rough brick without fading out, which surprised me.
