Designed with durability and quality in mind, we’ve opted to use authentic Austrialpin Cobra FM buckles for our dog collars which are the best of the best when it comes to quick release hardware. These buckles are made in Austria from stainless steel, aluminum alloy and brass components and have an 800lb working load rating. Our quick release collars are made from standard weight Biothane, which allows them to be adjustable in size. This makes the fit of these collars much more forgiving than a traditional belt-buckle style collar! Each collar features two button studs that keep the adjustment mechanism of the collar in place. The buckles are available in black in 3/4” and 1”, and coyote brown in 1”. The rest of the hardware on the collar is available in your choice or brass or chrome. Each collar is finished with a Strange Tails moon charm to match your hardware selection. A few notes: - The button stud components are made from solid brass/ nickel plated solid brass while the backing pieces are made from brass plated/ nickel plated iron. - While the quick release buckles we use are extremely durable, the black/brown finish will wear away with use. As such, we will not cover wearing of the finish or cosmetic damage to the quick release buckles under our warranty.
