When sourcing glitter lanyards, the primary concern is the base material and glitter application method. You should prioritize polyester or nylon webbing as the base for durability. For the glitter effect, heat-pressed glitter film is generally superior to spray-on glitter, as it prevents 'shedding' which can ruin professional attire. Ensure the width (typically 15mm, 20mm, or 25mm) aligns with your branding requirements, and verify that the breakaway safety clasp is included to meet workplace safety standards.
