Looking for a case for my Diasharp stones.

[bewing95]

I have 3 stones, 2 Diamond stones from DMT they measure 8" x 3" x 0.375" and a spyderco ceramic stone that measures. 3" X 8"X 5/16" i would like a sturdy leather case that holds all the stones in a trifold setup. So there would need to be room in between each stone so when folded up they all lay flat. Let me know a price.
