Super lightweight, durable, economical and easy to open, our J's Floating Fly Box keeps your flies safe and dry even if it falls in the drink. What's not to like? Made of solid EVA foam and covered with dark green fabric, it floats like a cork. The ripple foam inside has ridges for flies that are set 1/2 inch apart. The magnetic latch keeps the box tightly closed but is also easy to release. There's a label on the back cover for your name, address and phone number.
