The JMC Slim 103 is a box with magnetic compartments, designed for fly fishermen who want to keep their small hackle flies, hooks or tungsten beads neatly organized. Its rigid, transparent PVC structure ensures sturdiness and immediate visibility of contents, and includes 12 individual compartments with magnetic bottoms, preventing equipment from shifting, even when on the move. Ultra-thin and lightweight, this box is ideal for nomadic anglers looking for a practical, discreet and efficient storage system, whether at the water's edge or at the workbench.
