Yellow FBA massage cushion, perfect for activating the brain in your feet. With a dual structure of high and low resilience, it feels like walking on a sandy beach. Walking on soft sand puts a moderate load on your legs and lower back, which helps to strengthen your muscles. It's also recommended to stand on one leg or do yoga on the FBA. Just 3 minutes a day, it's easy to use, and you can train your brainstem and muscles with efficient training. - Color: Yellow - Brand Name: FBA - Product Name: Foot Brain Activation - Size: 46cm x 46cm, Height 6cm Thank you for viewing. I have home-cleaned it, but there are stains that won't come off and some tears. It is still usable. Please purchase with the understanding that it has these imperfections.
