You need a mark on glass or metal that holds up in a drizzle but still lifts clean when you're done. This UNI chalk marker does exactly that. Stays on in the rain. Wipes off with a damp cloth. No scrubbing, no residue. The 2.5mm chisel tip gives you bold, even strokes for signage, pricing boards, or workshop markings. One thing to note: non-porous surfaces only. If it's porous, it'll soak in and you won't get it out
