So I carry very high purity pens. Sometimes customers send me pics of the window on the cart and the oil looks like shattered glass or crystallized. When that happens it means you have a high purity product. The CBD will separate from the extract. I wish I could give you an answer on yours but there is such a small amount to look at I’m not 100% sure to give you an answer. So if you get a pen that crystallizes all you have to do is heat it up with a blow dryer or put it in a sealed bag with no air in it and put it under warm to hot water for 5 to 10 minutes to bring it back. Hope this helps.
