Our "Happy Birthday" message mugs come pre-made with a "Happy Birthday" message already at the top of each mug for milestone birthdays. 2020 milestone mugs are for years ending in 0 or 5 (i.e. 1970, 1985) and birthdays from 100th to 21st. We do not customize these mugs in any way as they are pre-made and ready to ship the next business day. They make a great quick gift for when you want a more personal touch but do not have the extra time to create a fully customized coffee mug gift.
