[Secret Society Memoma] Adult Radio Calisthenics Cards

“Have you ever filled up a Radio Calisthenics card all the way to the end?”

That summer morning. The memory of rubbing my sleepy eyes, heading to the park, and getting a stamp—
This notebook lets us, now as adults, rediscover the “joy of collecting stamps” while feeling that sense of nostalgia.

“Radio Calisthenics Card for Adults” is a habit-tracking notebook where you set goals and add stamps or stickers each time you achieve them.
It’s packed with a laid-back yet earnest “reward system” designed to acknowledge those moments in your daily life when you’ve “given it a little extra effort.”
What goals you write in this notebook is entirely up to you.
A single stamp is all it takes to think, “I did a good job today”—
Why not gently add that little sense of accomplishment to your daily life?
