Carmel Jumbo Railroad Chalk is used to create bold, bright marks on various large surfaces, including industrial applications for marking purposes, but also great for creating temporary outdoor art.
Railroad Chalk - Jumbo
It is the only place I have been able to find black railroad chalk.. so I am very happy they provide it... they ship so it arrives intact and not broken up. The chalk is exactly what I need.
I did an art project for the indigenous children being found all over Canada with this chalk. We drew 1326 chalk hearts and still have an insane amount left over.
10/10 would buy again.
