Safety Information
Please note that Lefy services are not intended for diagnosing, treating, curing, or preventing any disease or medical condition. Information and guidance provided by Lefy services are for reference only and should not replace the services of health professionals or physicians. If you have any medical concerns or plan to make any changes to your health, sleep, or activity based on Lefy services, always consult your doctor. Never ignore or delay seeking professional medical advice due to information from Lefy services.

We are not liable for any health issues resulting from the information or guidance provided by Lefy services. If you choose to make changes to your health, sleep, or activity based on Lefy services, you agree to assume all risks. It is important to be sensitive to your body’s responses. For example, if you experience unexpected, recurrent, or prolonged pain, fatigue, or discomfort due to changes in health, sleep, or activity, consult a physician before continuing with these changes.

Be cautious when moving or handling heavy items, ensuring that the ring or any other Lefy products worn do not get caught in fixed structures or heavy objects. If your finger swells or becomes irritated due to the ring or any other Lefy product, remove it immediately. If symptoms persist after 2‐3 days without using Lefy products, consult a dermatologist.

Usage, Care, and Maintenance
Finger size may vary throughout the day, making it difficult to remove the ring at times. If the ring gets stuck:
‐ Wet your finger with cold water and mild soap, then slowly twist the ring to remove it.
‐ Raise your hand above your heart to lower blood pressure, then attempt to remove the ring.
‐ In an emergency or if discomfort occurs and you’re unable to remove the ring, seek medical attention immediately.

Clean the ring using a soft cloth or by washing your hands with mild soap and water.
The Ring X may wear out with showering, bathing, swimming, and snorkeling.
Avoid wearing the ring during heavy‐duty activities such as strength training, shoveling, or handling heavy tools, as well as when carrying objects made of metal, ceramic, or stone. Additionally, avoid friction between the ring and other rings or objects made of metal, ceramic, stone, or diamonds. The Ring X can get scratched and may also scratch softer metal jewelry or items it comes into close contact with, such as gold, silver, or aluminum phone cases. Some ceramic phone cases with soft coatings may also get scratched.

Keep the ring away from children. This product is not intended for individuals under the age of 18.
If you suspect a child has swallowed the ring, seek medical attention immediately.
Do not expose the ring to excessive heat, such as inside vehicles or under the sun.
Do not pierce the ring or its battery.
Avoid handling batteries or using devices and machinery containing batteries while wearing the Ring X. In some cases, if both the cathode and anode of another battery touch the ring, a short circuit may occur, similar to a standard metal ring. This could present a potential electric shock hazard. Take appropriate precautions to avoid such situations.
