It is a compact device that applies pressure to the LI4 acupressure point on your hand, located between your thumb and forefinger where the bone meets in a "V" shape. It's designed to provide natural tension and headache relief throughout the day. This is an all-natural, drug-free option for people looking for relief from pain caused by recurring headaches, migraines, eye problems, and fever. It can also help boost your immune system. This is a discreet and mobile way of relieving discomfort while still maintaining an active lifestyle. While other acupressure and acupuncture devices can be bulky, this goes where you go. For the best results, wear it on your non-dominant hand on the LI4 acupressure point. It fits like a glove. Available in Black, Blue, and Green.
