Perfect for summer, this line of Earthen Myrra bars leaves you feeling particularly fresh and clean. At Earthen Myrra, we follow a traditional soap making technique call the Cold Process Method. It takes 4 weeks to cure. Usually all the soaps are made in small batches on regular basis to maintain the stock. 8 Months( its safe to use even after 8 months but since these are natural soap bars and are all scented with essential oils only, the fragrance fades away)
