We want fans to celebrate their fandom by customizing and personalizing certain products. For this customizable product, we invite customers to tell us how they would like their preferred name or text to appear by typing it into the indicated field. However, because a customer can type proposed customization text into the field and complete the order through the website, not all proposed customization text will be accepted. Please note that Fanatics may reject and cancel any customization order for any reason, including messages deemed offensive or inappropriate.
