Tacky Fishings Tacky Fly Box might look like other slotted plastic fly boxes but has fundamental advantages over other fly boxes of this type. The inserts are made from silicone rubber, which has very low memory, so each individual slot of which there are 168 holds even the tiniest nymph or largest attractor in place regardless of how many times it's been used before. With a tough polycarbonate frame and strong magnetic closure this box resists cracking and abuse. Deceptively simple but genius at the same time, the Tacky Fly Box from Tacky Fly Fishing will keep your flies well organised and safely stored season after season. Constructed from polycarbonate, silicon rubber, magnetic closing and a good long metal pin hinge.
