We want fans to celebrate their fandom by customizing and personalizing certain products. For these customizable products, including jerseys, we invite customers to tell us how they would like their preferred name or other text to appear by typing that text into the field indicated. However, just because a customer is able to type proposed customization text into the field and is able to complete the order through the website, not all proposed customization text will be accepted. Please note, Fanatics may reject and cancel any customization order for any reason, including for messages that are deemed offensive or inappropriate. As a die-hard Boston Celtics fan, you take pride in having the best gear. Upgrade your collection by grabbing this 18oz. Personalized MVP Tumbler. It features crisp Boston Celtics graphics and the option to customize it with the name of your choice. Its insulated design will keep your favorite beverage at a great temperature, so you can stay hydrated while you cheer your Boston Celtics to a victory!
