Stimulates the "Neiguan" acupressure points on both wrists to alleviate nausea and queasiness from morning sickness. Easy to use, just wrap the band around your wrists. Made of silicone, so it's safe to get wet. The band length is adjustable in 12 stages, so it can be used by children and adults. Purchased in June 2024 and used for about 3 months. The color is pink. It can still be used, but please understand that it is a used item before purchasing.
