I purchased this new on Amazon last year for around 40,000 yen, but I haven't had a chance to use it, so I'm putting it up for sale. To check its condition before listing, I set it up indoors as a test. There were no particular problems, no air leaks, and it stood up properly. When it's fully inflated, there's a hissing sound from the inflation port, and it seems like a pressure relief valve is working. I'm not certain, so please take this as a reference. Everything in the photos is included. Regarding product precision and quality, it's made in China and seems to be in line with the price, but it appears to be usable without any problems, and I thought it was a well-made tent with very good cost performance. No claims and no returns, please.
