The CANDULOR MARKER is ideal for marking the registration plates of the CRS sets. For this purpose the plates must be slightly warmed up (e.g. with a Bunsen burner, lighter, etc.) and can then be marked with the CANDULOR Marker. The wax pencil is water resistant and ideal for marking/labelling smooth surfaces such as metal, glass, cellophane and resins. The markings can be removed with commercially available disinfectants/wipes.
