Dirt Road Candle Co Simply the Zest Wall Diffuser Refill

From DRCC: 

Take a bite of sunshine with this quintessential summer treat! This combination will make your nose do anything but pucker! Sweet and tart lemon custard notes, baked on top of a bed of buttery shortbread and topped with powdered sugar, we don’t call it simply the zest on accident! It’s a dream!
