We got tired of having to choose between pretty and practical.
Bon Maxie was born from the frustration of pretty things that didn’t work, and practical things that killed the vibe. So we started designing accessories that do both.
Where others add features for the sake of it, we add the ones you’ll quietly rely on every day.
Designed in Brisbane, Australia, by Clare—a detail-obsessed human who got tired of making do.
