Vorsk Bio-Tracer BBs
 in 0.20g weight are typically sold in 1kg bags containing approximately 5,000 rounds, rather than a single 6,000-round unit. For those specifically requiring 6,000-round quantities, the Nuprol RZR series (a closely related brand) offers 0.20g 
Bio-Green Tracer BBs
 in that exact volume.
