Fly Patch Mouton Square Type, No Pins 10cm x 7cm, White A fly patch is a versatile accessory that can be attached to waders, neck straps, sling bags, etc., to make it easier to take out flies when rigging, or to dry flies before returning them to the box. This item has been stored for a long time, but I believe it is unused. Since it has no pins, please attach a safety pin for use. Thank you.
