1 inch tall spikes pictured #4 in the image.

Not your average tree spike, these have a flat taper at the base of the cone for a different look. Made from steel with nickel plating. These are tall and bold, may stab, and may get in the way. If you have long hair, it will get caught on these. Solid spikes attach with a screw for a secure hold on your strap. These look great when done side by side on wide straps.

If you are unsure of the quantity of studs that will fit your strap, you may either inquire first, or order more than you think you need. I can refund an overage, but not charge more for extra (unless you make a new order, which is more complicated for both of us).
