This is an ad for a company that drop ships their product from another company that has made its business on offering production and fulfillment of canned (but customizable) 3D knit styles.
Very very much an ad, including the current top level comment from the looks of things.
It’s only missing em dashes. At least someone cleaned those out.
Are they dropshipping preexisting designs, or are they making custom orders to a knitting company?
Edit: totally sincere question, I don't know their process
