Hi Dredgtones,
You can have the mold returned from the factory with your new order. Please specify this when you order. The factory will keep you specs on file for future orders. Since it's a wax mold you'll want to send it in a box. As a general note to readers, customers can send their molds in either an envelope or a box---either one is fine. Most people make plastic molds and send them in a large envelope but if it's a hard mold just wrap it in some bubble wrap and send it in a box.
Regards,
John
