Grimas Tooth Enamel is an alcohol-based varnish that can be used to colour teeth, available in a range of colours:  Black, Nicotine, Red and White. To apply, dry the teeth with a tissue and then shake the Tooth Enamel bottle well. Apply the enamel with the brush provided and allow it to dry for a few seconds. You can remove the tooth enamel with a tissue soaked in Iso-Propyl Alcohol. (but be careful!)
