You're looking at a brand new 80 gram jar of alcohol based Carving Dye (No. 1 on the colour chart), great for highlighting crevasses, stampings and carving.
Alcohol dyes have the benefit of deeper penetration and faster drying times.
Simply rub this thick paste into carved or tooled leather with a toothbrush or with gloved hands, before quickly wiping off the excess carving dye using a dry cloth. If required a damp cloth can be used to remove stubborn stains. Repeat as desired. Once the finish you want is achieved, leave to dry before buffing with a lint free cloth and applying your favourite lacquer.
Please note this gel will dry rapidly, so make sure to wipe it off quickly. This is an excellent way to set your leather carving apart as well as saving valuable time that would be spent conventionally dyeing your leather.
