0.9375 inch tall spikes pictured #2 in the image. Available in raw brass or nickel plated brass.

Bark like a dog. Good boy! These solid brass 15/16 inch tall tree spikes are bold and dangerous. They tell folks "don't get too close". These are both stabby and get in the way. If you have long hair, it will catch 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).
