Query: Great birthday party activity

We got these for our son's 5th birthday party. He and his friends painted them as they arrived, then after cake put on the stickers. Once stickers were on, they raced them. They got to take them home (rather than the traditional goody bag of junk). My only complaint is that the stickers don't stick well. One also broke, although a year later, the ones that my boys made are still in tact.These were really great and served our purpose very well.
