Air Venturi BBs are better than the competition because they have a thicker coating and a smooth, firm surface that stays sealed against moisture. That's important, because pits or openings in the coating allow humidity to contact the steel core, causing rust. Most BBs you buy come from overseas and are transported on ships exposed to salty humidity, then spend weeks or months in a warehouse before you buy them. This allows moisture to work its way into your BBs unless they have a thick, solid sealed coating that prevents rust from forming. Unlike inferior BBs that have inadequate coating and start to rust and degrade after just 7 days, Air Venturi BBs are totally rust free even 60 days after being exposed to water. No more grabbing a container of BBs when you need them and finding a rusty mess. If you're looking for BBs that don't have to be used immediately because they're made to a higher standard, get Air Venturi Steel BBs today at Airgun Depot.
