The Simms Foam Fly Box is an updated version of Simms original models which were a hit among fly anglers. The Foam Fly Boxes from Simms Fishing are the ideal solution for transport and storage of fly fishing lures. The use of high density foam offers numerous benefits including increased durability and reduced water absorbtion. The boxes feature really neat magnetic closures to keep the lures in place where they belong, but not closed so tightly as to inhibit ease of use. Included with each box are removable fly pages that can be swapped out with standard models should the angler prefer. We offer all three sizes of the Simms Foam Fly Boxes: Small, Medium and Large.
