"The body is kept warm after bathing. The water is mild."

I am so happy with this product. I do not feel pain when the stones make contact with the skin as the surface is not so rough. I put them into the bathtub. The body is kept warm after bathing. The water is mild. I am going to use the stones for drinking water and cooking. Thank you!

"I believe I will find beneficial effects in the near future."

I am happy because: I have not found an effect yet as I started to use the stones about a month ago. I was so glad when I found this product on your website because I was searching for it. I believe I will find beneficial effects in the near future. I am wondering if the stones included in the single package are enough to enjoy negative ion effects?? I put some stones in plastic bottles. I think negative ions are generated as I find that something like bubbles are produced. I also put some stones in a net bag, and put the bag into the bathtub to enjoy tourmaline bathing. I am looking forward to tourmaline effects.

Other comments: I have been using 1/2 of the stones for drinking water and another 1/2 for tourmaline bathing. Is this OK? The instruction manual says that it is better to boil the stones on a regular basis. How often should I boil them? Do they continue to work forever?

[From Ion Trading] Thank you for your feedback. You do not need to use 500g for drinking water. About 10% of the content of the bottle will be good. i.e. 50g will be good for a 500ml bottle. I suggest you should use more stones for tourmaline bathing. You should boil the stones on a regular basis for about 10 minutes. The stones continue to work almost forever.

"Tourmaline water makes/keeps the whole body warm."

Reason(s) why I purchased from you: I have purchased a high performance negative ion generator from you. It worked well. I purchased this product as I thought it would also work.

Detailed review: I used a similar product more than 10 years ago. It worked. I purchased this product because I have poor blood circulation in the feet. Tourmaline water makes/keeps the whole body warm.

"The body is kept warm after bathing."

Reason(s) why I purchased from you: I have purchased the tourmaline sheet and ceramic balls from you. I believe you offer great products because you are a specialized shop for negative ion products. I am not sure if I can distinguish real tourmaline stones from fake ones.

Detailed review: Actually, I was using bicarbonate bath salt. I was happy with it but it was not affordable and I heard that the price would rise. I recollected about tourmaline. Tourmaline stones are great as they continue to work almost forever. Of course, I know various tourmaline effects as I conducted research on the stones. I thought I and my family members would enjoy the beneficial effects. I decided to use tourmaline again.

The body is kept warm after bathing as blood circulation improves. The skin is smooth. I can sleep better.

I have questions.

Q1. How long does it take for the bathtub to be filled with tourmaline water after putting the stones?

Q2. I use one net bag. Is it better to use 2 bags? I think water can contact with a larger area of the stone surface. Is this why you include 2 bags? I have just started to use this product and I will continue to use it.

[From Ion Trading] Thank you for your feedback. A1. We suggest you should immerse the stones 60-120 minutes before bathing. A2. Logically, water can contact with a larger area of the stone surface if you put the stones into 2 bags. However, we do not have data which shows the effectiveness. We include 2 bags so that you can use one as a spare.

"The stones make the body warm. I feel as if I am taking a hot spring. "

Reason(s) why I purchased from you: I thought you would offer reliable service as I found many reviews.

Detailed review: I use this product for tourmaline bathing. The stones make and keep the body warm. I feel as if I am taking a hot spring. I perspired more than usual even though I did not soak in the bathtub so long. The tourmaline water is very soft. I found these effects during my 1st tourmaline bathing.

"I am happy as the stones do not make a sound when they collide with another in the bathtub."

Reason(s) why I purchased from you: Other shops do not offer polished tourmaline stones which have rounded edges.

Detailed review: Our family members put tourmaline stones into the bathtub to enjoy tourmaline bathing. The tourmaline water is soft. We have other tourmaline stones. They have broken into pieces. The small pieces float in the water. I was searching for new and hard tourmaline stones. I googled and found your website.

I decided to purchase this product because I thought the stones would be good for longer-term use than the older stones as they have been polished and the edges have been rounded. I am happy as the stones do not make a sound when they collide with one another in the bathtub. I put the stones in a finer meshed laundry net than the one included in the package and enjoy soft water. I made a good decision to purchase. I am sure that this product will be good for longer-term use. I found small pieces of broken stones when I received the package. The net bag included in the package is the right size but a finer meshed laundry net is better.

"2 net bags were included in the package. I started to use this product as soon as I received it. "

Reason(s) why I purchased from you: I thought the price, the product content, the shipping fee and so on were comprehensively good.

Detailed review: The round shaped stones are great because I was searching for stones for tourmaline bathing. 2 net bags were included in the package. I started to use this product as soon as I received it. I am going to use the stones for cooking as the instruction manual says they are also good for it.

"The alkaline odor is removed and the water becomes mild."

Reason(s) why I purchased from you: This product is more affordable than similar products supplied by other companies.

Detailed review: I have been using tourmaline stones for drinking water for about 20 years. The alkaline odor is removed and the water becomes mild. I was using smaller tourmaline stones. I lost about half of them in the drain as I repeatedly boiled and washed them. These round shaped stones are great as they are not too large or small and I do not cut my finger because of the shape.
