It contains 200g of clay bath salt. Refill and gift set with wooden spoon and victorian style lid are available.
 
The clay we use for this bath salt is called zeolite clinoptilolite, a naturally occurring mineral of volcanic origin formed millions of years ago when lava and ash fell into the sea. Zeolite clinoptilolite has remarkable ion-exchange (Na+, Ca2+, Mg2+, and K+) and adsorption/absorption properties and consequent detoxifying effects. The finely micronized particle size of our clay (less than 20 microns, one of the finest you can get) has higher bioavailability which enhances the property mentioned above. Epsom salt and Magnesium chloride release Mg2+ in the bath which even augments the ion-exchange.
