↓ I have many other items for sale too (*´꒳`*) #naokoko This exercise ball can be used not only for Pilates and training, but also as a toy for children or for balance training. Having one allows you to easily do dieting, core training, and core strengthening exercises while doing other things. Children can also play on it. By adjusting the amount of air, it's easy for children to grip, and it's light, so it's also recommended as a toy! A straw for inflating the ball is included. Remove the cap and inflate with the straw. There may be a rubbery smell, but it will disappear in a few days. Because it is approximately 25cm in diameter, adults cannot use it as a balance ball. Also, due to safety and intended use, this product is not designed to be inflated as much as a typical ball. Please check my profile for other precautions before purchasing. ◆ Tips for inflating the ball Remove the ball's plug and insert the straw → While holding the plug, inflate with the straw → Hold the entrance with your finger to prevent air from escaping, and quickly insert the plug Material: PVC Size: Approximately 25cm Color: Blue Instant purchase is welcome!!
