About Lenny’s World

Hi there! I’m Eunji—a graphic designer and mom to Lenny, my endlessly curious & cheeky little guy. I started this brand in 2021 to share the kind of playful, meaningful designs we love in our home.

From fun tees to personalised prints, every piece is made to spark a smile, fuel curiosity, and celebrate all the wonderfully messy moments of family life. I hope you find something that feels like a hug for your family, too.
