My appologies Lemonade CG. I should have read the CGTrader license agreement in it's entirety and not rely on snippets of whatever the OP's managed to cut and paste.

The first paragraph:
"If the model is under Royalty Free license, you can use it as long as it is incorporated into the product and as long as the 3rd party cannot retrieve it on its own in both digital and physical form. You cannot resell the model you bought in its digital form and you cannot resell it in its printed form as a separate, single item. "
However, from my understanding, you can sell this if it is incorporated into another product. Again, it's best to clarify this with support@cgtrader.com and explain to them your intentions.
This is the agreement on this website. I've noticed that this can mean different things on different websites based on different media. So it's best to consult with support of whatever website you're on to determine what the exact definition is, as this can vary.
