Amazon カスタマー 4 I was looking for something like this and am happy with my purchase. It was a good price and had high reviews here on Amazon, so I thought it would be a good purchase.I've been using it for a few weeks now, and it's quite comfortable and is exactly what I was expecting it to be.I had been dieting recently, and it has helped me keep good posture and seems to help shape my abdominal region.
