Produced by VORSK Airsoft, these Airsoft BIO BBs are precision engineered 6mm BBs which are designed to be used in a wide range of Airsoft guns and replicas.

These particular BBs are BIO 0.20g BBs which are created from biodegradable materials so that they will gradually break down with time when exposed to natural environments. Touted as a more environmentally friendly BB, they are sometimes required by certain Airsoft sites to play.
