We've found this perfect durable, round 3mm cowhide leather--that was also made for boots! With an adjustable length of 40-77cm (15-30in), the leather can be adjusted for ease of wear. (Please note: because it is a thick leather, be sure to tug hard to adjust the length.) Each pendant is attached with a simple antique silver or antique gold bail. Available in brown or black leather. (We're sorry but we can't switch the leather color for pendants once they are made).
