Thank you for viewing. It has only been used a few times, and there are almost no noticeable scratches, as far as I can see. Please purchase with the understanding that this is a used item. -- Safe Material: Made from 100% natural rubber, not inferior recycled PVC material. The hardness and flexibility are moderate, softer than a hard golf ball and harder than a soft tennis ball, providing more appropriate force. This material is SGS certified and meets EU import standards. Effective Design: Length 13 cm, diameter 6.5 cm, weight 330 g. This peanut-shaped fitness ball has a wider area than a single ball, making it suitable for the back and lower back. Ease of Use: With a lightweight design and a gift bag, you can put the fitness ball in your handbag and take it out for fitness anytime, anywhere. Simply place the ball on your back and lean against a wall to roll it, or step on the ball with your feet to release fascial tension, while simultaneously strengthening core power and maintaining stability.
