The Medium sized Go To Fly Box is one we have been looking for for years. A swing leaf, slotted foam, and water resistant box made to hold up to 468 flies. This is a killer fly box. We have sold the larger versions with and without swing-leafs for years, this medium size is just what the trout fisher needs.
Water resistant gasket is built in, box measures 6.5" x 4.5" x 1.75".
