The Replacement Buckle for the Deluxe Grazing Muzzle is a plastic buckle with a loop of webbing attached to the female side of the buckle. You can easily attach this replacement without sewing by folding the loop over the metal ring and inserting the plastic buckle through the loop. Although missing in this photo, the male side of the buckle is also included and is attached by re-threading the webbing in the crown piece.
