Selectively usable buoy and water-filled punching bag and kit
摘要:
An inflatable bag is selectively usable as one of a buoy and a punching bag. The inflatable bag is inflated depending on the selected use, and the inflating is practiced differently depending on the use decision. When it is decided to use the bag as a punching bag, the bag is suspended, and the bag is inflated with water. An inflatable bag member and kit includes components suitable for the selected use.
