This is a well-constructed single sided slimline waterproof PVC fly box with a silicone insert.
Silicone can better withstand the wear and tear of flies being taken in and out, and do not tear as easily as EVA foam.
Another advantage of the silicone is that it holds its shape very well so it grips and holds flies in place better than EVA foam.
The clear covers make it easy to view your collection of flies and the clip locks securely seal the fly box.
The silicone insert has 121 offset slits to securely hold you flies.
Colour: Clear covers, grey case with green silicone inserts
Unit of sale: 1 fly box
