Kenko – Hayday Studio

Kenkō

Japanese for ‘health’

Kenko is an online subscription brand redefining everyday rituals with sustainable bamboo toothbrushes. The new branding needed to strike the perfect balance: versatile enough to be laser-engraved into bamboo, beautifully clear when printed on kraft packaging with soy-based inks, and bold enough to cut through the crowded eco-toothbrush market.

The result is a modern, mindful identity that feels both premium and approachable. Designed to resonate with eco-conscious consumers and influencers alike, Kenko’s branding and packaging celebrate simplicity, sustainability, and shareability—making health and planet-friendly choices feel effortless.
