The Revalution storage system is a spool system with a difference, EVA spools are the best way of storing long hooklengths but now pins are not required with the rotating plastic pin.
There is an area on the spool for easy rig identification, displaying Rig length, line diameter as well as hook size and type.
21 spools are supplied in a storage box which has a semi-transparent lid, helping to eliminate light from the box. Stickers can be added to the inside of the lid for further spool identification.
