Once you have placed your order, I will reach out by email to discuss your customization, or feel free to reach out to me first at katie@thefaithfulbear.com. I need to know what image you would like on your 15oz mug and what color/kind of glitter. If you can imagine it, I can create it. Specialty glitters or Clays like footballs or baseballs, hearts, stars, etc. are an extra $5.00.
