This was fun as heck lol! I learned several new techniques here too! All metal hardware, resin spikes (designed, printed, and molded by Fuzzworks- THANK YOU CHRIS!!)
They're removable so that the wearer can adjust between wearing it in fursuit and out of suit. The metal buckle is extremely heavy and I may look to find a plastic version with metallic coating for weight issues. This was my first go and probably not how I would go about attaching the spikes the next time, but came out gorgeous none-the-less.
I can add up to 7 spikes on fursuit size and 5 when out of suit.

Spikes may be added to any collar that I have on sale today as well!
