Does not affect. After the green peel on the outside of walnut is wrapped, there will be yellow stripes in walnut grains. That's the pair you bought. The buyer didn't clean it up. You can pick it up by yourself with a tool or a needle, or you can brush it up with a brush.

If the bone is good, it is a little yellow. You can trim it with a knife before playing. If it is yellow and the bones are not ideal, it shows that walnuts are not mature enough in the growth process and have no value to play with.

Walnut yellow tendon forms two arc rays from navel upwards, which are distributed in the middle of ribs. The color starts from the navel, from deep to light, which is the suture line needed for walnut growth.

When the walnut is cut along the suture line, it can be seen that the yellow color is gradually reflected from the inside of the core-shell from the inside out. So the most difficult thing is the yellow tendon near the navel of walnut. If the color is dark, it is not easy to fight even after surgery.
