Texel Japan OSTO (Ost) Medical Acupressure Band I started experiencing morning sickness as soon as I became pregnant, and I wondered when it would end... I bought this new when I was pregnant with my first child, desperate for anything that might help. It seems to work for some people and not for others. It worked for me. I kept it in a Ziploc bag, thinking I might use it again. (I didn't have morning sickness the next time, so I didn't use it.) It's also said to be effective for motion sickness. The box and instruction manual are not included. There are no noticeable stains, but please check the photos. Because it's made of silicone, there's a possibility that fine dust may adhere during packaging and shipping. I would like to do business with those who are not concerned about this. If you're suffering from morning sickness, please give it a try!
