2 Pcs Portable Breathing Necklace, Stainless Steel Whistle Necklace in 2 Colors, Anapana Breathing Necklace for Breathing Exercises, Mindfulness, Meditation, Lover, Women, Men

I was intrigued to see what these two items were used for, but I am still in the dark as to their purpose. Each necklace with a whistle like device is described as a breathing item, but nowhere do you see them in action in the item’s photos on the Amazon page. All you can see are images of people wearing the device hanging from a necklace. I just cannot see how that helps with breathing. Enclosed with the two necklace set is a letter that is very difficult to read and I found to be unhelpful as to how they should be used. It does not work as a whistle, which is another possible use, maybe it produces a sound which humans cannot hear? It is a perfect example of “lost in translation”. As just a necklace it’s different, as a breathing aid, I cannot see the benefit.
