For use within the Arrow Vault, the Magazine keeps your arrows sorted and protected. The magnetic closure, working with the rubberized cushioning, allows you to stagger your arrows, keeping the fletching from coming into contact with one another, and keeping the arrows from moving and shaking around within the Vault. It can also be used independently of the Arrow Vault, and work simply as a way to keep your arrows from moving within bow cases, on backpacks, etc. The Magazine comes in three different sizes, small, medium, and large. This allows you to choose the ideal fit for your arrow diameter: Small: .166”/4mm shafts Medium: .204”/5mm shafts Large: .245”/6mm shafts
