Our Citrus Crush scent notes include: sweet orange, grapefruit and lemon. Juicy mandarin orange and lemon top notes offer an immediate mood lift. The diffuser box was created with original art by Katie Garrison. The diffuser boxes also come with an insert to keep the diffuser and reeds in place. Upon first use, dip your reeds in the diffuser oil and then flip to face upright to begin scent diffusion. Flip your diffuser reeds as needed thereafter to refresh the scent flow.
