What’s inside
Every month’s mailing is built to be opened, used, and kept:
The letter
A story Kid Stoic lived that month, and the idea that helped him handle it.
A challenge card
One small practice for the next four weeks. It keeps the lesson alive all month.
A philosopher trading card
Collect the people behind the ideas.
A bookmark
The month’s lesson, where they’ll see it.
A sticker
Art for a laptop, bottle, or notebook.
A paradigm card
The idea in a few lines. Pin it. Keep it.
Why the extras matter
The letter starts it. The challenge card and collectibles keep it going between mail days — so it’s not a one-Saturday thing.
When it ships
Envelopes go out on the 15th of each month. Join by the 10th to get that month’s envelope. Addressed to the child. US shipping included in the $9.
$9 per month. That’s it.
Cancel anytime. No long contract.
Give them a reason to check the mail every month.
A Kid Stoic membership is a gift that does not sit in a closet. It shows up, with their name on it, month after month.
Add a note right after checkout. We’ll pack the first envelope so they know who sent it.
