Pumice Stone with Rope, Rugged Nature Genuine volcanic pumice!
 
Their 100% natural, non-shaped genuine pumice stones will do wonders for your feet and hands. 
 
Made from beach collected pumice (not energy intensive, glass 'pumice') each piece is truly unique and so size and shape varies. Average size is around 5cm x 5cm x 2.5cm but can be slightly smaller or slightly larger (though all perfectly functional).
