"Book Club" is a sophisticated twist to the classic black cherry. Top notes of black currant and apple brighten the red wine and black cherry heart of this fragrance oil. Aged oak and amber base notes highlight the merlot, while vanilla balances the sweet finish. Deep, dark, and luscious. So no, no leather or books smells in this diffuser. This is for all the moms who need to join a "book club".

At 6oz, you'll enjoy months of your favorite scents without flame or the electric use of a warmer. It comes with 6 all natural reeds so you can adjust (we suggest starting with 4 and then adding or subtracting) the scent throw according to what works best for you.
