Authentic Birkenstock buckles with antique copper finish.
Please see measurement photo for example on how to measure your existing buckle properly. Measurement is the pin/bar length.
Each buckle is embossed with the Birkenstock company's logo. They have been enameled several times for the greatest durability and are made of a nickel-free metal that has been treated to protect against corrosion.
Love the antique copper buckles on my olive green Birkenstocks .Much better than silver.
The only downside was the shoe store charge me $35 to change out my other ones as I did not have the tools to do so on my own.
Just the same I am very pleased.
