It's simple. Choose the product you like, then on the product page, upload the PDF file of your paper. For some publication mugs, you can choose what to be printed on the back side of the mug. You can choose pre-designed message, write your own message, or upload a figure/graph/logo.
After your purchase, we will send you mockup proof within 24 hours. And your order will be processed only after you approve the proof.
