Pigmented chalk spray which can be easily removed from non-porous surfaces (glass/metal/most plastics).

Excellent for outdoor marking out but will fade over time, dependant on the weather and foot traffic from several weeks to several months.

Easily scraped or scrubbed off with soap and water on non porous surfaces but porous surfaces need a pressure washer and/or elbow grease, neither of which currently sold by Flints.

Always test on an inconspicuous area before carrying out work in earnest, especially on porous surfaces as pigments can stain the substrate.
