Half inch tall spikes pictured #1 in the image. Available in raw brass or nickel plated brass.

Bark like a dog. Good boy! These solid brass half inch tall tree spikes are just what you'd expect to see on a collar sported by a Rottweiler at a junk yard. You'll also see them on collars worn by guys who want to let you know they are the alpha dog. These are a good height not to be too stabby or get in the way. 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).
