Pink plastic stabilizing brace, perfect for water sports. I used this for swimming as part of my rehabilitation after being diagnosed with spondylolysis of the fifth lumbar vertebra, about 6 times over 2 months. It stabilizes the lower back and improves core stability when walking or swimming in water. Manufacturer's suggested retail price: 6800 yen I am selling it because my back has recovered. I recommend it to those who are suffering in the same way. The belt is slightly worn, but there are no problems with its use. Shipping via Yu-Packet Post Box.
