Delivered in 11 days, took the largest size 3XL to its size 52 (the Chinese are small). I expected that for this money on the back there would be magnets on certain vertebrae. But here to the left and right of the spine are ordinary metal strips. A 14-year-old son has scoliosis-there is zero sense from these two strips. I did not forget to invest the selected gift when buying. For this with a stretch of 4 stars. Thank you.
