Our Silvie extension silicone lined aluminum beads are lightweight and long-lasting. To make an anchor row or beaded weft row, the beads allow stylists to softly and easily secure hair in place. The 5mm aluminum structure makes it simple to lock the bead (especially when used in combination with Silvie Hair Extension Pliers). The silicone liner preserves the hair while avoiding sliding. These beads have a chip-free color coating that matches the Silvie Hair Extension Hand-Tied Wefts and thread colors.
