Popped after less than 24 hours later

I bought these for my husband's 40th birthday and the "4" popped shortly after the very next day. I wanted to take pictures of him with these balloons thinking that they would stay inflated for a week. Well that didn't happen, the "4" balloon ended up popping no less than 24 hours later. Not what I expected and was a disappointment since I wanted to take some pictures of him with it.
