This is a bracelet made by myself of half round stitching leather and silver plated zamak. The quilted leather is 10x4.5mm, The magnetic closure and the infinity link is silver plated zamak. All the findings of this bracelet has a 8 micras sterling silver coating. To measure your wrist take the wrist circumference and specify the measure without adding extra space. On this measure I add the space needed to make it perfect.
