Power IonicsHandmade Beaded Bracelets for Men and Women, Tourmaline, Eye of the Tiger, Obsidian, Lava Stone 10mm Beads and 4mm Stainless Steel, High Elastic 17.5-21cm Size, Mens Beaded Bracelets

Nice piece, not too heavy on the wrist, very wearable with any outfit. Received just two days ago. I started wearing it almost immediately. Sceptical at first but after two days I am already seeing results. The constant ache I have had in my hand for the last six months is considerably less. My ankles are definitely less swollen. I have been wearing it 24/7 except when showeringTo all those who gave negative reviews should rethink. My sciatica was on the return and it has gone since wearing the bracelet. Give this a chance. As for no certificate. There is the equivalent on the base of the box and tucked inside the lid under the thin piece of foam I found the information on how it works. The important thing is not to get tourmaline (any not just this) wet it can be severely damaged

It staped the same day I got it you should not sell it anywhere it cost me nearly 30 pound what a joke

Not sleeping any better
