Perfect for the fly fishing enthusiast, the New Phase Waterproof Thin Fly Box is an essential addition to your gear. Outfitted with waterproof latches and high-density rubber seals, it ensures your flies remain securely sealed and dry, even in damp, riverside conditions. With the added advantage of magnetic inserts, flies are held firmly in place, while deeper compartments cater for larger fly sizes. The thin design enhances portability for tucking into a pocket or a pack.
