By Sunday Rain, this duo of bath crystals are designed to relax and purify, and refresh and unwind. Add three or four spoonfuls to a warm bath to watch the water turn charcoal with the Charcoal crystals, or berry pink with the Acai Berry, made with sea salt and charcoal and berry extracts. Enjoy a long soak with these crystals so you can wind down and achieve a more peaceful night's sleep.
