Pro Tip for Best Performance:

When working with fine leather or dense webbing at this 13mm width, use a precision punch tool to create neat, clean holes for the prong to sit in. For lightweight fabric straps, reinforce the prong area with a tiny bit of fusible interfacing or a fine eyelet to ensure the fabric remains crisp and free from fraying over time.
