You put up the sign. The rain erases it by lunch. Or you can't get it off the glass without a solvent. The UNI chisel chalk marker solves both. It sits on glass, mirrors, metal and windows through a full downpour. When you're done, one pass with a damp cloth and it's gone. Eight assorted colours in the pack, so you've got red for 'CLOSED' and blue for 'OPEN' without hunting for a second marker. Chisel tip gives you bold strokes or fine detail from one pen
