Each refill gives your home up to 100 days of scent-sational fragrance bliss. Our fragrance plug-ins feature an adjustable cap that offers a precise adjustment of scent strength so you can control how much you want to enjoy at one time. Our formula is gentle and created to showcase our naturally relaxing scent, Calm. Our custom Calm scent features top notes of lavender, coconut milk, and lemon, followed by Tonka, rose, vanilla, and bois de gaiac woods; it smells like drinking an iced lavender latte on a warm sandy beach. It smells a-a-amazing.
