0.25g Excel FastBIO 1500 BBs.
These BBs are manufactured by Excel in Japan. The high quality polish applied to every BB, makes these perfect for use in all upgraded AEGs, high end gas guns, and upgraded spring guns. The heavier weight of these BBs means that they have a better accuracy at distances when compared to 0.20g BBs. This brand is produced as a fast biodegradable BB, meaning that they decompose at a rate faster than that of standard formula BIO BBs. The product is shipped in a resealable bag which helps protect the BBs and slows down the decomposition time line. Decomposition begins when the BBs are exposed to any combination of sun, water, or soil.

*Do not expose BBs to moisture and then attempt to fire them, they may jam in the barrel!!
