Review on Rainbow Stress Relief Sticky Pack by Jason Cox

My 7 year old daughter bought these with her own money. Two days after pushing it, it exploded. Whatever was in those balloons got EVERYWHERE, but worst of all, a large drop fell squarely in her eye. She screamed and cried for half an hour because of the burning and it felt like "knives were stuck in her eye." We had to wash it off within minutes. It also got on her clothes, bed, iPad and floor. I hope what they're filled with isn't poisonous. She is 7 years old and played with him as intended - she crushed him with her 7 year old arms with normal force. This shouldn't have happened, especially after he only lasted 2 days.
