Like many parents, we purchased this too close to Halloween so it arrived after the holiday. And we were too lazy to return it in time. So now seeing if anyone else wants it ahead of Halloween! Never opened it, still in its original package it was shipped in. Purchased on Amazon but from the Spirit Halloween store. I included the size chart because it says “one size” but also says 8+ on the packaging. Spirit Halloween Kids Spongebob Squarepants Inflatable Costume
