Product information "REPAIRLUX® Touch-up Pen, black"
With the REPAIRLUX® touch-up pen for dark natural and artificial stone, you can colour damaged areas before sanding and can avoid a white haze caused by sanding and polishing agents. The black retains its colour tone when diluted and does not turn purple, as is the case with conventional coloured pencils, which are often used as an emergency solution.
