Chill Out Room

For those who remember a bit, this is a collector's item. I bought it many years ago and inflated it once.
I tend to keep interesting things, but since I never use it, I decided to sell it. I dug it out from the back of my storage, and since inflating it is quite a hassle, I considered selling it as-is in the box as junk for cheap. However, it was quite a topic of conversation back then, but I couldn't find any information online, nor any reference images. So, I decided to inflate it properly and take pictures. To my surprise, despite some minor dirt, it's still in good condition from back then, and it seems to hold air (though it might leak slowly), so it inflated properly.
As a result, my 10-year-old son was happy with it, saying we could still use it at home if we added lights, so maybe we'll keep it after all.
It would also look great hung from the ceiling as a light fixture.
Therefore, I'm willing to sell it to someone who wants it, even at a slightly higher price, but please ask any questions before purchasing.
