I have trialed various different combinations of materials to find the most suitable and the waxed canvas and pigskin model ticks all the boxes. The waterproof waxed canvas provides and airtight solution and the pigskin interior keeps your tobacco smelling fresh and true to its nature.  
 
Please note this purchase is just for the liner . Tobacco pouch NOT included . The liner does not seal the tobacco on its own so you will need a pouch that is suitable or need to purchase one from our catalogue.
