Kao-ka, thank you for your comment. How about this? If there is no purchase by 12/22, I will offer it to someone else. 45cm yellow balance ball, pins in the photo, and spares included. - Brand: gymnic - Model name: Gymnic Classic - Size: Maximum diameter 45cm - Color: Yellow - Accessories: Fixing pins Thank you for looking. I have four of these, and their conditions vary. Please refer to the photos. Some have noticeable stains and black marks, while others are relatively clean. All of them can be inflated and used. There are differences in appearance. Please consider this item, understanding that it is a used product.
