One of the problems that professional ceramic tile fitters are often faced with nowadays is making marks for cuts in ceramic tiles without them disappearing just by touching them or through the action of water, but which can be cleaned when you don’t need them without leaving a trace or a stain on the surface of the ceramic tile.
Paying due attention to this very specific need of professional ceramic tile fixers, the RUBI offer includes crayons.

RUBI crayons have been specially designed to write on surfaces like glass, glazed ceramic, natural polished stone, metal or other hard to mark surfaces. Large for ease of use.

Available color: blue.
