While I use many of these stampings in my other Etsy store. www.etsy.com/shop/twistedsisterarts many of my fans wish to have access to them. To that end, here's a store that you can browse, buy and create to your hearts content. You'll find the stampings and eyes here. One of these days I'll complete the series and provide wire that I use too.
These take a 14mm to 16mm eye glued from behind. I like to run a chain, doubled over and rethreaded upon itself to make an interesting bail. It's got great depth, and detail.
The size of the single piece is 26mm x 26mm.
The finish is fine silver plating. I have these custom plated for me by a fabulous company that works with high tech manufacturers. He's more expensive but in the years I've worked with them they've always have a high quality finish.
I could also change the patina or the finish of the piece by using this technique as seen in this video.
