The Cracker Jacks Super Poppers are great little gems that will really go off with a BANG! These extra loud poppers are great for parties and events because they will definitely get everyone's attention. There are 20 pieces in each can and this is a 4-pack. Now, that's a savings of 2 over buying the cans individually! Not recommended for children under 8-years-old and they are for outdoor use only.
