I think they would have sold more if they had been a little more creative with the different styles. If they had made one with the SSE pattern on it I might have thought about getting one. Just putting a generic Mickey on it was kind of boring.
I asked how much the bigger ones were years ago. They were expensive. In the $100 range. Yoga balls are cheap, durable and fun. I got my kid one for $20.
Not surprised they closed.
