This is a double teardrop-type punching bag from Winning. The upper punching bag can be used after inflating it with air, but the lower punching bag immediately loses air even after being inflated. It is a junk item. Therefore, it can actually be used as a single. Repairing the punching bag can be done through a sports shop, as Winning does not deal directly with individuals, but it is possible. I can provide you with contact information and details if you wish. All parts are included, and I will also include a molten air pump and lubricant as a bonus. Training with the double was very aggressive, and I actually became able to land punches. Thank you for your consideration. High-quality black punching bag from Winning, perfect for training. - Brand: Winning - Color: Black - Accessories: Strap, handle, hardware Thank you for looking.
