Available in several versatile sizes, Swarovski Elements Crystal Round Sew-on Stones are drilled with two holes, one on each end. The reflective quality of the foil backing enhances their sparkle. These stones feature a smooth, flat back that is ideal for sewing onto fabric. They can also be linked together with jump rings, used as unexpected design components and more.
