My crystal water bottle was such a fantastic purchase! Love, Love, Love it! I have had my Miijo bottle for a while now with the "clear quartz" and I DO think I feel more energised, positive and clear headed than usual. I haven't always been a big believer in crystals but I'm 100% supportive of anything that can help bring balance and harmony into my life. Lets face it, drinking out of glass bottle with a pretty crystal is way more fun then a cheap plastic water bottle. Miijo products get a 5 star from me!
