Hitting these balls makes it difficult to hit them far unless you can hit the sweet spot. This helps you understand the contact point. You can also strengthen your wrists, and as a training exercise other than batting, you can also train to improve your grip strength. 【Condition】 As shown in the photos, there are some scratches, wear, and deterioration from use. There are no major damages or cracks. They are still in a condition that can be used for practice! Please check the condition in the photos. We hope to sell them at a slightly lower price to those who need a large quantity ✨ 【Accessories】 Balls only, 17 pieces 【Packing/Shipping】 We will carefully pack them in a reused cardboard box.
