Personalize these acrylic toppers with your name or initials! These will ONLY fit the Stanley H2O 40 oz and 30 oz. We cannot guarantee fit on dupes or other brands. If you would like to bring your cup in store so we can make sure to get an exact fit let us know. Keep in mind that they are custom items, and therefore the turnaround time will be longer. To ensure timely delivery, place orders for them separately from other items and allow 7-14 business days. Feel free to leave a note at checkout with your desired wording and colors, or you may send the details to amycox132@yahoo.com. Note that monitors vary, and we do our best to accurately show the colors. If you'd like to see them first-hand, you can FaceTime with us or view them in person at the store. Final sale--no refunds issued for custom orders!
