Midges, Meat, and Mayflies - Oh My! Our triple layer design allows you to effectively hold a ton of different sized flies. The magnetic bottom handles all the small flies. The leaf has our time-tested slit blue foam that really grips the big, heavy stuff. The top is set up to hold and protect dozens of dry flies. It will take a beating. Fits easily in a fishing shirt at 6" X 4" X 1 5/8". This box has been awarded the Ka-Ching award at this years Fly Fishing Retailer World Trade Expo.
