Ice Screw Protection. Good protection for the sharp & delicate tips of ice screws during transport. New design that fits various diameters of screws. The bottom of each cap is pierced to release any water & dampness that could cause rust, a problem with the old caps. Whilst using the screws the protection can be hooked onto the screws handle where it doesnt risk being lost. This is a solution to two problems: rust on the blades of screws & losing the caps whilst out.
