OSTO Morning Sickness Band Ice Blue Disinfected with alcohol wipes. I only used it twice after purchase because my morning sickness naturally subsided. Please understand that this is a used item. The following is the product description: Easy to attach, the OSTO medical acupressure band is gentle for everyone. OSTO stimulates the "Neiguan acupoint," a pressure point that alleviates unpleasant nausea from morning sickness and motion sickness. OSTO is a medical acupressure band that stimulates the "Neiguan" acupoint. ■ Size: 21mm x 15mm x 227mm (set of 2 for both wrists) ■ Weight: (per band) 24g ■ Remarks: Materials: Silicone rubber, iron spring (body) Precautions for use: Always wear on both wrists. Do not use for purposes other than the intended use, and do not use in conjunction with other medical devices.

Cyband Mama does not treat symptoms, but rather encourages measures and alleviation of symptoms through acupressure point stimulation, and its effects vary from person to person. The marks from the acupressure button may remain on the skin for a while, but this is temporary. If symptoms such as itching or pain appear on the skin, discontinue use and consult a medical professional. Please be aware that the effect will not be achieved if the point is off. Be sure to follow the instructions and set it at the appropriate point. Do not wear it on any other part of the body.
