0.20g Tokyo Marui FastBIO 1700 BBs.
These BBs are produced by Tokyo Marui out of Japan. Tokyo Marui is the original manufacturer of airsoft products, so it is a fact that they produce the best quality BBs on the market. These BBs are recommended for use in all types of airsoft guns. These high polish, extremely high-quality BBs work best in tightbore and other high tolerance barrels.These BBs are produced as fast biodegradable, meaning that they decompose at a faster rate than 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!!
