Our Gold and Metallic confetti is not biodegradable. The foil is a mylar material which looks great, beautifully sparkles in the air and are very popular. They are also one of our most common used cannons for most events.
We suggest that they metallic mylar/foil confetti to be used indoors. They are not biodegradable and will not break down overtime outdoors.
If you are shooting the metallic cannons outdoors, please pick up them up because it would be considered littering and will be left blowing around until they are picked up by someone.
