How the wonder works
Tell us about them
Share a little bit about your child — what they love, what they did well, what makes them them. Your details make the letter truly theirs.
We write their letter
Our letter writers craft a one-of-a-kind letter, print it on premium nostalgic stationery, and seal it in a beautiful envelope.
Magic arrives in the mail
Written and printed within 2 business days, then mailed by USPS to land in the last 3 business days on or before the date you chose — a surprise to open, hold, and keep long after the moment has passed.

Questions, answered
When will our letter arrive?
You choose the arrival date when you order. We write and print every letter within 2 business days, then mail it by USPS from Chicago, Illinois on the day that lands it within the last 3 business days on or before your date. Please choose a date at least 7 business days out; orders after 11 p.m. Central count as the next day.
Will it arrive before Christmas?
Yes, when you order by December 15, 11 p.m. Central. Santa and Elf letters ordered after that arrive after Christmas.
Where do you ship?
We ship by USPS anywhere in the United States, from Chicago, Illinois. Shipping is included in the price of every letter.
How does the personalization work?
Each letter has its own short set of questions — the things only your family would know. We write the letter from your answers, so no two letters are ever the same.
Can I add the Keepsake Frame to any letter?
Yes. The frame is a +$12.00 add-on on every letter's page, designed to fit any letter and any occasion.
