I picked up a few touchstone kits from Best Buy, they all came with the touchstones and touchstone matte backs. I put one back on my phone and will keep another one in case the one on my phone gets scratched.

I have ONE touchstone back for sale. It's brand new and still has the plastic cover on it that you peel off before using. I'll also throw in the back part of the Zagg shield. I decided to only use the front side.

So you'll get a 100% new matte back that works with the touchstone and the back of the Zagg kit which will cover the back if you want it.
