You're looking at 100ml (3.5 fluid ounces) of brown colour, water based, odour-free, irritant-free, non-toxic, environmentally friendly, leather burnishing agent.
Simply apply a small amount to the flesh side or edge of your vegetable tanned leather, spread evenly then firmly work into the leather with a smooth wooden dowel or piece of scrap leather, reapply as necessary to leather and leave to dry.
Shake well before use.
Excellent for burnishing edges as well. The fibres will be compacted and a glossy finish will appear leaving the flesh side of your leather so smooth and attractive it won't even need any lining!
