The Preston Absolute All-Round Hooklength Box is designed specifically for storing large quantities of 3" through 9" (75 – 225mm) hooklines. The Preston Absolute All-Round Hooklength Box holds up to 800 hooklines in total! The gasket helps prevent water from entering the box which is sealed by two clips and additional magnets on the sides. The box is made of an ultra-durable ABS plastic and has fixed pins that are perfectly positioned. Each type of hookline can be clearly marked on the labels provided. Furthermore, all types of leaders (up to 225mm) can be neatly stored in the Box, because the pins are mounted far enough from the sides, ideal for hairrigs!
