Leikedun 2Pcs Anxiety Relief Necklace Portable Stress Relief Mindful Necklace...

These worked well

Garbage stay away

I've quit vaping so using this along side nic pouches I've stuff some cotton inside to restrict it so it's more mouth to lung and it's good so far

Not good just a tube, like sucking on a whistle, you can add cotton wool but still naff

Not work for me but mabe work for others

Nice and solid but chain was quite short. I made it into a bracelet.

Very nice items and very usefull. I don't have to think a lot if I ehxale enough and good. I controle better my deep breathing and that means I dive more quickly in a relaxation state of mind.

Rubbish don't work.
