My Bomber collar that I made for FC.
I got the resin piece custom made from this girl here: http://www.artfire.com/ext/shop/studio/Lutrasaura_Resin_Dreams
Should go check her out.
The collar is a new thing that a friend of mine figured out. It's an X base collar that's super cute~

If you're interested in a custom collar like this, feel free to send me a message.
