How does it work the branding and data privacy when I retail jewelry from wholesalers?

When you sell a product you downloaded from a wholesaler, only your business will be branded to your customer. The wholesaler will not be promoted anywhere. In another words, it will be a dropshipping transaction.

Also, your customer information will be kept private on your side of the transaction, besides the customer shipping address, because the wholesaler will need it to ship the product directly to the customer.
