The Nuprol RZR Bio BB 0.25gr 2200rds are biodegradable and come in a very handy bottle that is resealable and has a capacity of 3500 bb's.

These bb's from Nuprol are of a very good quality and are very neatly polished so you can get the most out of this bb. The bb's have a size of 5.95mm with a margin of +/- 0.01mm so they are also perfect to use in precision barrels.
