These are A-1 quaity silk worm cocoons from Bombyx silk worms. The cocoons have been heat treated so the silk worm is killed. That's why you hear a rattle when you shake the cocoons. An ounce of silk cocoons is about 24-30 cocoons depending on the size of the cocoon.
Cocoons can be spun from the cocoon or you can reel them with the right equipment. The cocoons can be dyed with any dye that does wool. They can be spun them by themselves for a textured yarn or blended into any other fiber for texture and added luster.
The cocoons are pure white and SOME HAVE A FEW YELLOWISH SPOTS ON THEM. THIS IS A NATURAL OCCURANCE.
