Accurate marks on any material
On some materials – glass, tile, metal, and PVC for instance – a carpenters pencil just won’t cut it. Luckily, there are other options for leaving a mark on those hard-to-write surfaces. You’ll find some of these pens, pencils, and markers at your local homecenter, but I’d also recommend a trip to the art supply store. There you will find marking solutions for all sorts of surfaces.
