This is a very nice fly box from Perrine. The box is jet black composite with perforations. The holes are reinforced by metal grommets which also attach the metal strips on the inside of the box. The metal strips are like little ledges with spring inserts. The flies stay securely attached and are easy to remove. There is a metal band that reinforces the entire box.
Stamped into box: Sterling Quality, Perrine
Measures 6 1/8″ x 3 7/8″ x 13/16″
