This is the Vision Slim Fly Box in size large. This fly box is part of Vision's Slim series, a set of fly boxes that are ultra thin and allow you to fit comfortably into your vest pocket.
The slim boxes are no bigger than a traditional sized fly box but still give you plenty of space to hold a large selection of your flies.
There is also a special box that is sold separately that has a magnetic base to prevent the flies/hooks from dropping out.
This Vision Slim Fly Box is a large size and is very slender at only 12mm thick. This box also comes decorated with a special fish camo print.
Box dimensions: 187mm x 98mm x 12mm
