This is a large pool, measuring 120x30. It doesn't require inflation and is supposedly ready to use in 1 minute. However, when it arrived, it was quite heavy, and I didn't end up using it. I think it would be good for an indoor ball pit, etc. Originally priced at 4,980 yen on Rakuten. I am also listing this on other flea market apps, so I will remove the listing if it sells. Instant purchase is welcome.
