For curious kids ages 5–12 (5-7 with parent)
Twice a Month, a Letter Arrives From Someone Who Changed History
Real letters. Real adventures. Real imagination!
Twice every month your child receives letters from Lewis and Clark, Ben Franklin, or Amelia Earhart. Hand-crafted on aged parchment, packed with maps, activities, artifacts, or other fun surprises in an envelope addressed to your child by name.
Like a pen pal from the past.
From $14 a month.
Not a workbook. Not another app. An envelope in your mailbox with your child's name on it, from a real person out of history, that makes them ask when the next one is coming.
Your child's first letter ships within 3 business days.

YOU KNOW THAT FEELING...
Your child deserves more than another
hour of screen time.
You watch them light up at a great story. You see the spark when they ask "but why did that happen?" You want to nurture that curiosity — the kind that turns into a lifelong love of reading, learning, and thinking deeply about the world.
But between school, activities, and the constant pull of tablets and streaming services, finding something that genuinely captivates your child — not just educates them — feels like searching for treasure without a map.
History textbooks feel dry. Library trips get forgotten. And the books you carefully select sit half-read on the nightstand.

Each delivery is carefully crafted — so every letter, artifact, and activity feels like pure magic.
Benjamin Franklin

He tells the real story of running away to Philadelphia, flying a kite into a thunderstorm, and starting clubs, libraries, and fire brigades along the way, all with the wit that made him America's favorite Founding Father.
