Purchased around the summer of 2023 and used a few times, but I'm selling it because I no longer use it. It can be used by filling it with water and inflating it. The first photo shows it inflated with an air pump after filling it with water. Please check the condition of the product in the images. Please refrain from purchasing if you are looking for a perfect item, as this is a used item stored by a private individual. To prevent product switching and avoid trouble, returns and cancellations are not accepted after the product arrives. Please understand this beforehand. Please purchase only if you agree to these terms.
