This is the Edge Pro Apex Shapton Glass Stone set from "The Great Satan". It's about a year old and in very good condition with a lot of life left in the stones. It is complete except for the little squeeze bottle and the towel (it was basically just a blue paper shop rag). It has the following Shapton Glass Stones:
The 220 stone has some uneven wear at one end due to using it to smooth out the flat of a Tanaka blade (see pics).
The 1K has a crack through the middle from dropping it. It doesn't effect its performance and you can't even feel it when you run your finger over it.
This unit has served me well but I have switched over to freehand so it's time to pass it along. Asking for $175 (includes domestic shipping) or will trade for a Naniwa Snow White 8K, a Gesshin 8K, or a large Takashima Awasedo from JKI. Will consider trade for other finishing stones also.
