Enjoy daily crystal vibration hydration. These high quality glass bottles hold approximately 16 ounces of (crystal-charged) water and include a bonus neoprene sleeve. The Indirect-style bottles have a separate glass chamber at the bottom filled with crystal chips. Crystals can be swapped out at your discretion, and you need not worry about toxic stones as they aren't directly exposed to your water. Although the bottles are easy to clean/use, it's worth noting that the crystal point cannot be changed. Available in your choice of Garnet, Sodalite, Amethyst, Iolite, Rose Quartz, Clear Quartz, Golden Quartz, Peridot or Moss Agate. Drink up!!!
