I have had a few customers ask me about sea salt, so I finally found some that I could sell at a reasonable price! These sea salts are completely natural and are sun bleached. Finest quality you can find! They come in a one ounce bag which is enough to last most people about 3-6 months depending upon how many crystals or coins you wash. Sea salts are used to clear negative chi from crystals upon purchase. It is also advisable to cleanse them about once a month. Hanging them out in the moonlight overnight once a month is said to recharge the crystal. If you use these to cleanse I-Ching coins, it is recommended that you soak them in a glass container for 7 days and nights before use.
