There is no problem using it in combination with other companies' sports necklaces.

Please check the instructions for use provided by your manufacturer.

This product is also suitable for customers with pacemakers. Please use our products for body care and daily health management.

It is safe to wear during pregnancy. Support products such as the Deep Balancer Necklace and our HARAMAKI product are popular among many pregnant women for daily health management, preventing chills around the stomach and leg cramps.

Although this varies from person to person, some people may experience physical discomfort or drowsiness. This is thought to be a positive reaction as the body's immune system begins to function and return to its natural balance by using this product. (This is based on our own wear data.) If you feel unwell, do not push yourself and gradually increase the amount of time you wear it.

This product promotes fluid balance in the body and increases metabolism, which may cause itching around the neck or other areas where the product is worn. We recommend that you do not overdo it, but instead take it off and put it on frequently and gradually increase the amount of time you wear it. (This is based on our own wear data.)
*This is based solely on wear data. If you are allergic to minerals, please consider not using this product.

There is no problem with wearing it while bathing. The special wire and titanium parts used in the Deep Balancer are designed to be extremely resistant to sweat and water.

If the stain is noticeable, wash it with water or apply a mild detergent diluted with lukewarm water to a cloth and wipe the entire surface lightly, then remove the moisture with a dry cloth and allow it to dry completely before using again.

You can have your favorite products maintained (wire maintenance and fastener replacement) at our official online store and authorized retail stores.
One of the features of the Deep Balancer Necklace is that it can be used semi-permanently with repeated maintenance.
To ensure longer use, we recommend performing wire maintenance once a year.
Fastener replacement maintenance also includes wire maintenance, so please make use of this as well.
Please check the maintenance page for details.

We recommend size L (50cm) for the average adult male. We recommend size M (45cm) for slimmer individuals, women, and children.

Depending on how you use it, the wire of the necklace may stretch over time and become too soft, which may cause the clasp to come off easily.
If the wire comes off frequently, it is time for maintenance. Please order wire maintenance from our official online shop.
