Product Description
CONCEPT
CO: Together
RUNNER: Runner
CO&RUNNER is a necklace developed with the concept of "a product that supports people as they work towards their goals and moves forward together," and is designed to promote physical recovery.
The neodymium magnet (200mT) embedded in the silicone loop is intended to improve stiffness and blood circulation in the area where it is worn.
Please use this product to address physical discomfort you experience in your daily life and for post-exercise care, and help improve your quality of life (QOL).

Fits any occasion: work, sports, or everyday use.

Choose a magnetic necklace by color.
This product combines the efficacy and effects of a home-use permanent magnet magnetic therapy device (regulated medical device), such as improving stiffness and blood circulation in the area where it is applied, with a fashionable design featuring colorful colors.
With its subdued color scheme, it can be used by people of all ages. Enjoy CO&RUNNER magnetic accessories during sports and everyday life.
Medical device certification number: 304AFBZX00053000

Colorful attachments
The attachment has a three-tiered structure, with each part featuring a different color and surface finish. We hope that the vibrant colors will help boost your motivation while you enjoy the visual appeal.

Maximum magnetic flux density (200mT)
This product features a powerful neodymium magnet sealed within a loop. With a maximum magnetic flux density of 200mT/millitesla, it improves stiffness and blood circulation.

Platinum Silicone Loop
The loop material uses platinum silicone. Compared to ordinary silicone, it has almost no odor and is stronger. It is a safe and secure silicone that is often used in hygiene and medical-related products.

Magnetic attachment
The attachment part uses a magnet, making it easy to attach and detach.

Kiyoseki
This ring contains a rare ore that is only mined at the Gozairi Mine in Katashina Village, Gunma Prefecture.
