"I ordered these for my son's birthday party. The kids had to have a lot of help making them. The kids wanted to wear them right away, but of course had to wait for the glue to dry. Making the masks was the first party activity and most guests were able to wear their mask before the party was over, but the monkey masks took longer. The monkeys were the only ones I would not suggest using. Since the elastic string attaches by the ears, (which have to be glued on) it comes apart too easily. A crying little monkey at your b-day party doesn't make for merriment. As long as you have time to let them dry well the masks are a nice keepsake, just don't expect to be able to make them and wear them within a 2 hour party."
