・This is a vinyl pool that we used at home. Our child is now in junior high school, so we don't think we'll be using it anymore, so we're offering it to someone who needs it. As a bonus, we'll include a disinfectant for the pool. This is unopened and unused. ・It was used for two years, about 3 times in total. ・There are no noticeable signs of wear. I inflated it for the listing, and it inflated normally. We haven't put water in it, so please consider that. ・I think it's a large size. The approximate dimensions are 250cm x 160cm x 50cm high. It was a comfortable size for two children, and adults could also relax in it. An electric pump is recommended. For your reference. Due to the size, it will be packed tightly in a cardboard box for shipping. We plan to ship it on the upcoming weekend after purchase.
