I just finished adding a bunch of stabilized Koa blocks to my web store.
Last I looked there were 72 blocks with prices averaging between $35 to $65 each. A few are lower and a few higher. This is the best selection of stabilized Koa blocks I have ever had. All were stabilized by K&G.
This link will take you to that section of the store.
These are a few of my favorites;
Fiddleback Red Koa
Blister or Birdseye Koa
Crushed Velvet Koa
No matter how I tried I could not get the photos to look nearly as good as they look in real life. If I could figure out how, I think the best way would be to take a video in the sunlight. Then you would see that this wood reflects a metallic flash like a bicycle reflector in your headlights.
