At Billet-Doux, we believe the most profound messages are still the ones that engage our senses. We were founded on the art of the love letter, translating its intimacy and anticipation into the universal language of scent and light.

Each of our creations is a piece of correspondence, a story waiting to unfold. Our fragrances are composed like verses of poetry, designed not just to scent a room, but to evoke a feeling, stir a memory, and create a sanctuary for connection. We hand-pour our candles in small batches, choosing vessels that feel as beautiful as they look—from the luminous glass of a heartfelt Confession to the enduring ceramic of a solemn Vow.

Our mission is to help you write your own love stories. Whether it’s the constant presence of a Sonnet diffuser filling your home with a signature scent, or the flickering flame of a Secret Note on a quiet evening, Billet-Doux is an invitation to slow down, connect, and transform a simple moment into something romantic.environmentally responsible.
