The condition varies, but the frequency of use is about 2 hours in a match format, followed by about 15 minutes once or twice a week for warm-ups, mostly opened from September to November of this year. *Last year's balls have already been sold, so these are only from this year.* Over 100 balls will be shipped in a plastic shopping bag, making them easy and convenient to carry and store. Cardboard boxes are difficult to carry. These balls can be reused for various purposes, such as crafts, batting practice, massage, and dog toys. They are suitable for those who want to reuse them. These balls were used outdoors, and I have cleaned them as much as possible with a vacuum cleaner, but please consider the photos if you are concerned.
