Thank you for your question.
Your question was: “Hmm … you fill candy or toys in piñatas or people who order piñata, fill them in it ??? ”
Long Answer: I think that finding the filler for the piñata is one of the most fun aspects for a piñata party. I was just at an Indian Jones piñata party for a 6 year old. In addition to the candy, toy spiders snakes and skulls fell out of the piñata. This was incredibly fun for the boys who were attending the party. I think that I heard more comments about the toys that fell out then the candy.
Advice: Go to a craft store or a party supply store to find fun filler. Craft stores usually have a larger selection of more unique items but party stores have the trendy stuff.
PS. Yes I know that party stores sell piñatas. I am not concerned. The quality is usually so inferior to the authentic Mexican Made piñatas that Piñata Supply Co sells. I am not afraid of my boss losing sales.
