Gender Reveal Party Poppers are filled with Holi Color Powder (corn starch and food grade dye) and biodegradable confetti circles. The circles come in quarter size pieces and dime size pieces. Our simple point and twist cannons are easy to use and clean up is a breeze with our biodegradable powder and confetti (we still recommend cleaning up as best you can!). Choose from 12" or 24" length poppers.
